Olympus製顕微鏡用の透過照明光源として使用されているLED MWWHL4と顕微鏡用コリメートアダプタCOP1-A
マウント付きLEDを動作させるにはLEDドライバが必要です。LEDから出射される発散ビームをコリメートするには、コリメートアダプタ(別売り)を使用します。適切なLEDドライバについては下の表をご参照ください。各LEDに対して必要なコリメートアダプタは、下の青いInfoアイコン()の情報をもとにお選びください。
マウント付きLEDの特長
- 波長範囲:265 nm~5200 nm(右の表をご覧ください)
- 白色、広帯域、デュアルピークのLEDもご用意
- 内蔵メモリにLED動作パラメータを保存
- 熱特性を最適化して安定した出力光パワーを実現
- 顕微鏡とSMネジに対応したコリメートアダプタをご用意
- カスタム仕様の電源用に4ピンメス型コネクタもご用意(別売り)
コリメータ無しのマウント付きLEDでは、深さ6 mmのSM1内ネジを有するヒートシンクの端面にLEDが1つ取り付けられています。Ø30.5 mmのヒートシンクの付いたLEDの外径はSM1レンズチューブと同じであるため、30 mmケージシステムにも取り付けられます。動作中の発熱量が大きい一部のLEDは、より大型のヒートシンクに取り付けられています。この大型のヒートシンクは通気口の付いたØ57.0 mmのプラスチック製筐体に納められていますが、前面にある4つの#4-40タップ穴で 30 mmケージシステムに組み込むことができます。
各LEDにはそれぞれのLEDに関する情報(電流リミット値、波長、順方向電圧など)を保存するEEPROMが付いています。当社のLEDドライバDC2200、DC4100またはDC4104を使用する場合は、これらの情報をスマートセーフティ機能でご利用いただくことができます。
マウント付きLEDは熱的な安定性が優れているため、LEDの温度上昇に伴って光出力が低下するという問題は生じません。詳細は「安定性」タブをご参照ください。
なお、マウント付きLEDは家庭用照明としては作られておりませんのでご注意ください。
LED出力光のコリメート
当社の調整機能付きコリメートアダプタを用いると、Ø25 mm(Ø1インチ)レンズは最大11 mm、Ø50 mm(Ø2インチ)レンズは最大20 mmの移動が可能です。各調整機能付きコリメートアダプタにはSM2内ネジ付きアダプタが付属しているので、LEDを当社のØ50 mm~Ø50.8 mm(Ø2インチ)光学素子用レンズチューブなどのSM2ネジ付きコンポーネントに簡単に取り付けることができます。このアダプタには、ARコーティング付き非球面コンデンサーレンズの付いたタイプと付いていないタイプがございます。
また、ARコーティング付き非球面レンズを組み込んだ顕微鏡用コリメートアダプタもご用意しております。これらのアダプタは、Leica DMI、Nikon Eclipse Ti、Olympus IX/BX、Zeiss Axioskopなどの一部の顕微鏡の落射照明ポートにも接続できます。当社ではマウント付きLEDにあらかじめ顕微鏡用コリメートアダプタを取り付けた製品もご用意しています。
当社の多くのLEDについて出力光をコリメートする方法をご提案しています。詳細は下の青いInfoアイコン()をクリックしてご覧ください。「コリメーション」タブでは、LEDのコリメート方法について詳細がご覧いただけます。
ドライバ
当社では、こちらのLEDに対応するドライバとしてLEDD1B、UPLED、DC40、DC2200、DC4100、DC4104の6種類をご用意しています(DC4100とDC4104にはDC4100-HUBが必要です)。適合するドライバについては下の表、ドライバの仕様については「LEDドライバ」のタブをご覧ください。ドライバUPLED、DC40、DC2200、DC4100、DC4104は接続されたLEDのEEPROMから電流のリミット値を読み取り、最大電流値を自動的に設定してLEDを保護することができます。
マルチLED光源
当社のマウント付きLEDに当社の他の部品を組み合わせて、カスタマイズ可能なマルチLED光源の構築が可能です。例えば、当社の汎用的なSM1レンズチューブシステムや30 mmケージシステムを用いて、そのような光源を組み立てることができます。詳細な型番のリストや構築方法等については「マルチLED光源」タブをご覧ください。
自由に設定ができる統合型の4波長高出力LED光源もご提供しています。
出力光パワーの比較
個々のLEDから出力される実際の光スペクトルや全光パワーは、製造工程や、温度や電流などの動作パラメータによって異なります。適切なLEDをお選びいただくために、出力光パワーの典型値と最低値を明記しています。各マウント付きLEDは、最大電流において少なくとも最低値として明記された光パワーを出力します。公称波長の異なるLEDの出力光パワーを互いに比較できるよう、下のグラフのスペクトルは各LEDの最低値の光パワーでスケーリングされています。これらのデータは代表例です。すべてのマウント済みLEDのスペクトルデータをまとめたエクセルファイル(規格化データおよびスケーリングデータ)はグラフ下のリンクからダウンロードいただけます。

当社の340 nmマウント付きLEDの典型的な寿命は3,000時間以上です。45日後の試験対象ユニットは初期出力パワーの90%以上を持続しています。
LEDの寿命および長期的なパワー安定性
LEDの特性の1つとして、時間の経過と共にパワーが自然に低下することがあげられます。ほとんどの場合、パワーは緩やかに低下しますが、急速な低下や完全な停止、あるいは故障が突然起こることもあります。LEDの寿命は、LEDの種類ごとに規定されたある割合のLEDが、あるパワーレベル以下に低下するまでの時間で定義されます。寿命測定のパラメータはBXX/LYYで表され、ここでXXはその種類のLEDで寿命が過ぎた後の出力パワーが規定値のYY%以下になるLEDの割合を示します。当社では、LEDの寿命をB50/L50で表しますが、これはその型番のLEDのうち50%のLEDの光パワーが規定の寿命がきた時に初期値の50%以下に低下するという意味です。例えば、定格出力パワー150 mWのLED100個のうち、50個の出力パワーが規定の寿命を過ぎたときに75 mW以下に低下するということです。
右のグラフは、340 nmマウント付きLEDについて45日間にわたる長期安定性試験を行った際のデータ例です。340 nmマウント付きLEDの典型的な寿命は3,000時間(約125日以上)となっています。LEDをONにした後にパワーがわずかに低下しているのは、動作開始から数分間の典型的な動きです。これはLEDが温まり、熱的に安定するまでの時間に相当します。グラフは1個のLEDに関する性能を示しています。LEDの性能は仕様の範囲内で単体ごとに異なりますのでご注意ください。
最適化された温度管理
こちらのマウント付きLEDの放熱は安定な出力のために最適化されています。ヒートシンクはLEDマウントに直接取付けられていて、熱的接触は適切な状態になっています。これにより、LED接合面の温度の上昇によって生じる光出力パワーの減衰を最小に抑えることができます(左側のグラフをご参照ください)。
Video Insight(How-to動画):LEDからの出力光をコリメートする方法
LEDやその他の寸法の大きなインコヒーレント光源からの光をコリメートするのは、意外にも難しい作業になる場合があります。エミッタのサイズ、コリメートレンズの焦点距離と開口数(NA)など、それらのすべてがコリメートされたビームの特性に影響します。また、レンズが適切な位置にあることを見極めるのも難しい場合があります。動画では2種類のコリメート方法をご紹介しています。さらに、NAと焦点距離の異なる2種類のレンズを使用して、レンズのNAを大きくするとLEDからより多くのパワーを集光できる代わりに、コリメート光が発散する割合も大きくなることを示しています。
LEDからの出力光をコリメートする2種類の方法
上記のVideo Insight(How-to動画)でご覧いただけるように、LEDの出力光を適切にコリメートするためには、選択したコリメートレンズとLED間の距離を調整する必要がある場合があります。コリメート光は光路の局所的な領域でしか得られません。このコリメートされた領域では、ビームの発散は最小限に抑制され、どの位置でも収斂することはありません(比較については下の写真をご参照ください)。どのようなビームを用いても完全にコリメートすることはできず、コリメート光も一定の割合で徐々に発散します。LEDのようなインコヒーレントな光源では、エミッタのサイズが大きいほど発散の割合が大きくなります ここではコリメート光を得るための2つの方法についてご紹介します。
方法1:LEDを無限遠で結像させる
- LEDの電源を入れます。
- コリメートレンズから約30~60 cm離れた場所にビューイングスクリーンを置きます。
- コリメートレンズとLEDの距離を調整して、LED像をビューイングスクリーンに映し出します(下図A)。
- ビューイングスクリーンをLEDからさらに遠ざけます。
- スペースがある限りステップ3と4を繰り返します。
- ビューイングスクリーンをコリメートレンズから約30~60 cmの元の距離に戻すと、収斂しない均一なビームが見えるはずです。十分にコリメートされていれば、ビームは円形に近く(わずかに多角形の場合もあり)、LEDそのものの像がはっきり見える状態ではありません。画像Cは、コリメートされたビームの例です。
- コリメートレンズの最適な位置を見つけたら、コリメートレンズの位置を固定します。
注: スペースの制約により、この方法を有効に使えない場合があります。スペースが限られている場合は、方法2(下記)の方が有利な場合があります。
方法2:ビームの広がりを利用してコリメートレンズの位置を設定する
- コリメートレンズから距離Lの位置で予想されるビーム径(D2)を求めます。

図1: コリメートレンズの後方のビームの予測される広がり。サイズdのLEDからの光は、直径D1、 焦点距離fのレンズで集光され、レンズ後方では発散角Φが生じます。レンズから距離 Lの位置でのビーム径はD2 = D1 + ΔDになります。
図1は、LEDから放射されてコリメートレンズを通過するビームの伝搬の様子を示しています。コリメートレンズ後方で予想されるビーム発散角(Φe)は、次の式で与えられます。
ここで、dはLEDの横方向の大きさ、fはコリメートレンズの焦点距離です。コリメートレンズから距離Lの位置で予想されるビーム径(D2)は、以下の式で計算できます。
ここで、
式1を式3に代入すると、ΔD=Ld/fとなり、次の式が得られます。
- LEDの電源を入れます。
- 距離Lの位置にビューイングスクリーンを置き、コリメートレンズの位置を調整してビューイングスクリーン上でビーム径が D2となるようにします。
- これがコリメートレンズの適切な位置ですので、コリメートレンズの位置を固定します。
下の表では、Ø25.4 mm(Ø1インチ)非球面コンデンサーレンズ(ACL2520U)を用いた時の、LEDごとの視野半角(Half Viewing Angle)の違いを例示しています。 一部のLEDについては、下のInfoアイコン( )をクリックして 「Collimation Adapter」タブをご覧いただくと、推奨されるコリメート用の光学システムを見ることができます。

顕微鏡の照明ポートに接続されたマルチLED光源
カスタム仕様の顕微鏡照明用マルチLED光源
当社では下でご紹介しているマウント付きLEDを2台もしくは3台使用して、お客様の仕様に基づくマルチLED光源を組立てていただくのに必要なアイテムをご用意しております。 以下の構成例のように、光源は顕微鏡の照明ポートに用いられるように設計されています。 しかし、当社のSM1シリーズのレンズチューブや30 mmケージシステムを利用すれば、その他のアプリケーションにも組み込むことができます。 LED内蔵で、お客様が自由に設定できる4波長高出力LED光源もご提供可能です。
設計と構築
まず、光はレンズチューブに取り付けられたレンズによってコリメートします。 キネマティックケージキューブに取付けられたダイクロイックミラーが、複数のLEDからの出力を結合します。 マウント付きLEDは、小型のT-Cube LEDドライバLEDD1Bで駆動できます(電源は別売りです)。LEDドライバLEDD1Bを用いることで、各LEDの出力を個々に変調でき、最大1200 mAの電流を供給することができます。 LED光源は、最大定格電流を越えて駆動しないようご留意ください。
カスタム仕様の光源を設計する際は、下記掲載のマウント付きLEDと併せて、LEDの波長の中間に位置するカットオフ波長に対応するダイクロイックミラーもご用意ください。 適切なダイクロイックミラーを選べば、側面に取り付けたLEDからの反射光を反射し、光軸に沿った光を透過させます。 大部分のダイクロイックミラーは、「ロングパス」フィルタであることにご留意ください。つまり、カットオフ波長よりも長い波長の光を透過し、短い波長の光を反射します。 ロングパスフィルタを使用して3台以上のLEDの光を重ねるには、より長い波長のLEDを後ろから順番に重ねてください(下記参照)。 長い波長を反射し、短い波長を透過させる際にはショートパスフィルタをご使用いただけます。 下の3つの表で、適合するダイクロイックミラーとLEDの組み合わせのサンプルをご紹介しています。
各光源に適切なARコーティング付きの非球面コンデンサーレンズの選択も必要です。 光源を組立てる前に、マウント付き高出力LEDからの光をコリメートしてください。詳細は「コリメート」タブをご覧ください。 付属の固定リングSM1RRを用いてレンズチューブSM1V05内に非球面レンズを取り付ける際は、調整機能付きスパナレンチSPW801のご使用をお勧めします。 適切にコリメートされたLED光源からのビームは、ほぼ均一で、60 cmの距離では大きく拡散することがありません。 適切にコリメートされたビーム光の例は「コリメート」タブからご覧いただけます。
全てのLED光源がコリメートされたら、各LEDアセンブリの先端に取り付けたレンズチューブSM1V05をレンズチューブカプラ SM1T2を用いてそれぞれのケージキューブポートC4Wに取付けます。 ダイクロイックフィルタをダイクロイックフィルターホルダ FFM1に取り付け、そのフィルターホルダをキネマティックケージキューブプラットフォームB4C(/M)に取り付けます。 プラットフォームB4C(/M)を付属のネジを使ってキューブ底面に軽くネジ止めして取り付け、定位置まで挿入・回転させます。 プラットフォームを要求された位置にアライメントしたら、ネジをしっかりと締め付けます。 複数のケージキューブと顕微鏡用アダプタを接続するには、レンズチューブカプラSM1T2とØ12 mm~Ø12.7 mm(Ø1/2インチ)レンズチューブSM1L05を隣接したケージキューブの間にお使いください。 最後に、各プラットフォームB4C(/M)の回転、チップ、ティルトを調整して反射および透過光ができる限りぴったりと重なるようにアライメントします。
ご要望に応じて、3台以上のLEDを取付けるマルチLED光源も構築可能です。 接続できるLEDの数は、光のコリメートの状態と仕様範囲におけるダイクロイックミラーの性能によって実用上の制限を受けます。 荷重の大きいマルチLED光源はØ25 mmまたはØ38 mm(Ø1.5インチ)のポストで支持します。

However, when the maximum forward current of LEDDIB to M310L1 and M340L5 is adjusted, The measured optical power can not reach the minimum output power of M310L1 and M340L5. What might be the cause? jjadvani

 (posted 2023-09-26 05:59:21.0) Dear Mr. Ramsoge, thank you for your enquiry. I will personally reach out to you to provide more information. Thank you. Warren Massey
 (posted 2023-09-06 13:17:47.347) The datasheet says to power this LED with no more than 1000mA, yet all the optical ratings for the LED are when it is powered with 1000mA suggesting a lower/safer current not be used during operation (i.e., no current safety margin). That leads me to believe that 1000mA is actually a NOMINAL maximum current and that there is some tolerable variation allowed around that value. What is the acceptable range of maximum operating current? FWIW, looking at your suggested companion "upLED driver", it says: "LED Current Accuracy: ±(1% + 10 mA)" which would suggest that 1110mA is an acceptable upper current limit given that this suggested driver might supply just that. Looking at your suggested companion "basic LED driver", its current limit is a manually-adjusted potentiometer, whose setting depends upon on some adjacent ballpark silkscreen labels so I doubt it's much better at establishing a ±10% current limit. hchow
 (posted 2023-09-11 05:33:30.0) Dear Mr. Massey, thank you for your feedback. We suggest our customer to not exceed the maximum driving current of the LED, as adverse effects to the LED can occur. If too much current is used, the LED will start to overheat, causing a colour shift, or burn out, and at the worst case, fragmentation of the LED. The upLED LED driver is able to read the EEPROM chip on board the mounted LED and is able to automatically adjust the current. Moreover, there is a current limit switch on the manual LED driver, LEDD1B, which limits the maximum driving current. In either cases, the maximum current is not exceeded. Pedro Mecê

 (posted 2021-12-08 15:18:07.843) Hi,
the LED works as expected. However, this is a mounted LED, which means people will keep threading it in and out all the time. It is super annoying to do so with the cable.
My suggestion:
It would be perfect if one could disconnect the cable from the LED, such that while mounting one wouldn't have to mind the cable.
Moreover, having the cable like this, makes you break it quite easily, as you keep twisting it..
I believe this applies to all mounted LED..
Thanks

 (posted 2018-11-29 07:17:48.0) This is a response from Wolfgang at Thorlabs. Thank you very much for your inquiry!
The quality of the collimation, i.e. the remaining divergence, will be roughly the same with or without a diffuser. The diffuser smoothens the intensity distribution of the beam and makes it more homogeneous. It will also smoothen the edge of the beam a bit so the beam would look a bit wider. The main disadvantage of a diffuser is that the transmitted power would be lower than without a diffuser due to absorption and reflection. user

The forward voltage of LEDD1B is high enough to drive M415LP1, but the maximum current is 1.2 A only, whereas the maximum drive current of the LED is 2 A.

The selection look adequate for collimating the M1300L3.
Basically the distance of the lens to the LED should be the back focal length.

I see high frequency fluctuations on the flux output generated by the LED at 660nm.
I use the M660 and the LEDD1B controller in continuous mode, below the maximum current (using the setting 1000 mA, to a rather high setting in this mode ~50 to 70% of the knob range).
Fluctuations appear at the level of the kHz: we sample our signals at about 1.05 kHz, and observe sporadic drops (down to ~30% of the nominal value). Are you aware of a feature of the controller or the LED driver or of the LED electronics which would be related to this effect? wskopalik
 (posted 2017-06-22 06:01:47.0) This is a response from Wolfgang at Thorlabs. Thank you very much for your inquiry!
The only expected fluctuation on the LEDD1B would be the ripple on its current which is specified to 8mA max. You use the LEDD1B at about 500-700mA so the ripple would be less than 1% of the current and couldn't account for the large drops in power you see.

 (posted 2016-06-22 01:59:06.0) Response from Bweh at Thorlabs USA: Due to the large divergence angles of these LEDs, the 2" diameter lenses will collect more power than the 1" optic. For example, with a 60deg half angle divergence LED and a 20mm (or 12mm BFL) 1" lens, you will only be capturing about 56% of the LED output, which may or may not be suitable depending on your application. Should you need to use the 1" LED collimators, you would need an SM2T2 and we can provide the corresponding 2" adapter without the lens inside. ludoangot

 (posted 2014-08-20 12:09:39.15) Dear Thorlabs,
The thorlabs LED collimation page describes using an SM1 lens tube and aspheric lens. It seems you advise we buy an adjustable 1/2" lens tube and extend it with a 0.30" adapter.
Since ThorLabs sells an adjustable 1" lens tube (SM1V10) this seems rather redundant, unless the thread inside the LED casing does not allow it to collimate. There is no information about the depth of the SM1 thread inside the LED casing.
My question is this: Could you tell me whether SM1V10 would be able to collimate the LED on its own, or does it require SM1V05 and the 0.30" spacer? If this is the case, I suggest you extend the thread on the LED case, if possible, to simplify the process.
Kind regards,
Sam S myanakas
 (posted 2014-08-20 11:11:48.0) Response from Mike at Thorlabs: Thank you for your feedback. The thread depth is stated within our mechanical drawings (http://www.thorlabs.com/thorcat/MTN/M530L3-AutoCADPDF.pdf) which can be found by clicking on the red "docs" icons by the items numbers below. The thread depth for these LEDs is 6 mm. Based on this feedback we have added this information to the Overview tab of the web page. The SM1V10 can be used in place of the SM1V05 and SM1L03 pairing. However, the current recommendation allows for a slightly longer translation range of the optic due to the 7.6 mm depth of the internal threading in the SM1L03. The Collimation tab has also been updated to include the use of the SM1V10 as a collimation solution for these LEDs. Carlo.Vicario

In this range you will see a linear relationship, however we have no information how this relationship changes in the range from 350mA to 700mA. We have tested this LED only at 700mA as this is the maximum drive current our heat sink system can also manage. You can find the manufacturer spec sheet of this LED on our website here: http://www.thorlabs.com/thorcat/23300/M1050L2-MFGSpec.pdf
Our spec sheet can be found here: http://www.thorlabs.com/thorcat/23300/M1050L2-SpecSheet.pdf
In general information about this relationship if available, can be found in the manufactures spec sheet. I hope this information helps you further, please let me know if there is anything else you need. a.andreski

 (posted 2013-08-23 12:24:08.587) Dear Sir or Madam,
I have a question concerning the mounted LED system you supply. We are using it as a BIAS illumination source in a measurement setup.
I was wondering what the EEPROM on the PCB is for. Is it in any way affecting the current supply of the LED? In particular, is it possible that it creates some noise on the current supplying the LED?
Thank you in advance for your help!
Best regards,
Jan Haschke tschalk
 (posted 2013-08-26 10:08:00.0) This is a response from Thomas at Thorlabs. Thank you very much for your inquiry. Our Mounted High Power LEDs are all equipped with an EEPROM where the operating parameters are stored. The LED drivers DC2100, DC4100 and DC4104 read out the EEPORM and set the maximum operating current to the stored value. This way a current overload can be avoided. The driver LEDD1B is not able to read out the EEPROM and the current limit has to be set manually. The EEPROM will not cause noise to the current supply. I will contact you directly with more detailed information. jvigroux
 (posted 2012-09-24 10:22:00.0) A response form julien at Thorlabs: Than you for pointing this out. We corrected the presentation on our website so that now the wrench recommended is the SPW801. We will send you a replacement for the lens together with the new case. gir
 (posted 2012-09-20 16:20:24.0) One other thing: On the application page where it explains how to collimate the LED, it says to use a SPW602 spanner wrench to secure the aspheric lens with one retaining ring on each side. I did this, and the SPW602 carved a circle on the front surface of the lens. Please change this text to instruct people to use a different spanner, so they don't inadvertently scratch their collimating lens. gir
 (posted 2012-09-19 20:09:14.0) Hi: I have a minor issue to relay about the packaging of the mounted LEDs. I bought an M735L3 late last week and received it today. The plastic case it comes in is not well designed or built. Specifically, the red latch on front broke off while I was trying to figure out how to open the case. And it took two of the black plastic hinge-posts with it, so even when I put the latch back on the case, the case won't stay shut anymore. It seems silly to provide these in a hard shell case if the latch can't withstand a bit of force from a novice case-opener. jlow
 (posted 2012-08-30 14:23:00.0) Response from Jeremy at Thorlabs: Is your power supply a voltage source or is it a current source? It is highly recommended that you drive these LEDs with a current source instead. If you used a 5V constant voltage source (@ 3A), then you will most likely be injecting 3A of current into this LED and thus destroyed it (max. current for MCWHL2 is 1.6A). Please note that the typical forward voltage for the MCWHL2 is only about 3.5V. It could also be that you have not connected this correctly. I will get in contact with you directly to check on the details on your setup. doron.azoury
 (posted 2012-08-30 11:16:39.0) Hi,
I just recieved the MCWHL2 LED. I control it by a DC power supply. I set the voltage limit to ~5V and tried to rise the current, but the LED doesn't seem to be working. Am I doing something wrong? (the DC supplier can deliver up to 3A) jlow
 (posted 2012-08-22 08:19:00.0) Response from Jeremy at Thorlabs: We do not have a precise number for this, but based on some old data, the rise and fall times are both on the order of 20ns or so. riclambo
 (posted 2012-08-20 13:48:19.0) Hello Thorlabs. I am using the 385 nm LED and I need to know its on-off switching time, particularly its off time i.e. when you turn it off, what is the extinction time of the after glow. Even if this is not known precisely, as order of magnitude value would be very useful. jvigroux
 (posted 2012-07-16 09:20:00.0) A response from Julien at Thorlabs: Dear HongYang, thank you for your inquiry! The curve displayed on our website is aimed at showing the effect of long term thermal stabilization, ie. heat transfer from the LED chip and PCB to the heat sink. Should the thermal exchange channel be poor, it can be that the temperature of the LED will settle at a too high temperature, which would lead to the situation displayed by the curve "LED with poor thermal management". The time scale for this effect is indeed in the seconds range and the curve was plotted accordingly, which can give the impression that the rise time is slow. This rise time is however much shorter than visible on this curve and is typically of a few 10's nanoseconds. The main limitation in this case is the capacitance of the LED and thermal effects as plotted on the aforementioned curve will only be relevant at on a much longer time scale and much lower in magnitude than the capacitance related limitation of the rise time. LuHongyang
 (posted 2012-07-16 03:08:26.0) The figure in the tab 'Stability' shows that the rise time of these LEDs is several seconds. So does it mean that LED cannot be fully charged when modulated at a high frequency? If so, that will introduce instability to the power in that situation, I suppose. Thanks a lot. Hongyang. jvigroux
 (posted 2012-07-13 12:05:00.0) A response from Julien at Thorlabs: Thank you for your inquiry!

 (posted 2012-05-30 06:45:00.0) A response from Julien at Thorlabs: thank you for your inquiry! the 500mA that are specified by the manufacturer of the LED in the MFG spec sheet apply only for the bare LED. Due to the fact that the LED is mounted on a large heat sink and that the thermal coupling to it is very good, the LED can be used in constant mode at currents up to 700mA. andrew_yablon

 (posted 2011-12-06 05:58:00.0) A response from Julien at Thorlabs: Thank you for your inquiry! The approach you intend to use is unfortunately only partially possible. The problem is that the voltage drops across the LEDs will add up when they are connected in series. The specified operating voltage for this LED is 6.8V. As the compliance voltage of the LEDD1B is typically 12V, you will be only able to connect a maximum of two LEDs in series, unless you reduce drastically the current. I will contact you directly to discuss your application and see which approach is the best suited for your application. sborn

Both of these drivers can be operated in constant current mode, trigger mode, and modulation mode.
Regarding the condenser lens, we would recommend using the ACL2520. Its diameter is 25 mm, so it is compatible with our SM1 lens tubes.

 (posted 2008-10-31 09:50:24.0) Response from Laurie at Thorlabs to atashtoush: To modulate the MBLED you will need the LEDD1 T-Cube LED driver and a TPS001 15 V power supply. You will need to provide your own signal generator with the following requirements: Minimum Strobe Pulse Width: 50 µs Strobe Turn-On / Turn-Off Time: <25 µs. The maximum flash rate obtainable with the LEDD1 with full 100% modulation will be around 3 kHz with a maximum strobe effect up to 10 kHz.
If you need to modulate at higher rates you would need to consider a laser driver. Depending on the driver, you can indirectly modulate to about 250 kHz. Above that value you need to RF modulation directly into the LED anode. atashtoush

コリメートアダプタは、ネジアダプタSM2T2およびSM1A2を用いてLEDに取り付けます。同じセットアップでØ57.0 mm筐体の付いたLED(上記参照)に取り付けることも可能です。
- 小さいf値(約0.8)のARコーティング付き非球面レンズ
- Leica、Nikon、Olympus、Zeiss社製の一部の顕微鏡に対応
- ビームのコリメート・集光の調整が容易
- 上記LEDに使用する場合にはカプラSM2T2およびアダプタSM1A2(いずれも別売り)が必要
マウント付きLED(上記参照)の出力光のコリメート用として、Ø50 mmのARコーティング付き非球面コンデンサーレンズ(EFL:40mm)を取り付けた、コリメート用アダプタをご用意しております。ARコーティングは2種類(350~700 nm、650~1050 nm)、筐体は4種類ございます。筐体はOlympus*、Leica、Nikon、Zeiss社製の一部の顕微鏡の照明ポートに適合するよう、アリ溝またはバヨネットマウントが付いています。対応可能な顕微鏡については下表をご覧ください。
使用するLEDの波長が透過しない素材やARコーティングを有するアダプタを使用することは推奨しません。深紫外域LEDにはUV溶融石英(UVFS)製のレンズが必要です。多くの一般的なガラスでは350 nm以下の光は透過しません。 1050 nm以上の赤外域LEDは、コーティング無しのコンデンサーレンズを使用してコリメートが可能です。 ACL5040Uは下記のコリメーターパッケージに使用されているコーティング無しのØ50 mmレンズで、380~2100 nmの波長範囲で使用できます。365~1650 nmのLEDにご使用いただけるその他のコリメータについては、上の各製品の表内の青いinfoアイコンをクリックし、「Collimation Adapter」タブをご覧ください。
上記のLED光源は、上の写真のように、カプラSM2T2およびアダプタSM1A2(いずれも付属していません)を用いてコリメータに取り付けられます。このアセンブリは、LED筐体を外して他のLED光源に簡単に付け変えることができます。
*BXおよびIX顕微鏡の透過ランプハウスポートの光学設計により、Olympus社のアダプタを別途ご購入いただくことが必要な場合があります。
