- 生物試料を損傷させないように保護する
- フォトディテクタなどのセンサにダメージを与えることなくパルスレーザ光を測定する
- 物質内で蛍光や非線形効果を得るために励起を行う
パルスレーザ光のパラメータは下の図1および表に示します。参照用として、計算式の一覧を以下に示します。資料を ダウンロードしていただくと、これらの計算式のほかに、パルスレーザ光の概要、異なるパラメータ間の関係性、および計算式の適用例がご覧いただけます。

当社では、幅広いパワーメータ&エネルギーメータ用コンソールやパワーセンサ・エネルギーセンサを操作するためのインターフェイスを取り揃えています。 主な仕様は下記でご覧いただけるので、お客様の用途に適したモデルをお選びいただけます。 下記のほかに、センサ内蔵のワイヤレスパワーメータや小型USBパワーメータもご用意しております。
当社のパワーメータ等用のコンソールやインターフェイスは、Cシリーズのセンサとお使いいただく場合は接続したセンサの種類を自動的に認識し、電流値とそれに応じた電圧値を測定します。 Cシリーズのセンサは、コネクタ内に感度特性の校正データが保存されています。 コンソールは、入射波長に対応する感度の値を読み出し、パワーもしくはエネルギの測定値を計算します。
- フォトダイオードセンサは、入射光の光パワーと波長によって決まる電流を流します。 この電流は、トランスインピーダンスアンプに送られ、このアンプから入力電流に比例した電圧が出力されます。 フォトダイオードの感度は波長に依存するため、正確なパワーの測定値を得るためには、コンソールに正しい波長を入力する必要があります。 コンソールは、接続されたセンサから、入力された波長における感度を読み取り、測定した光電流から光パワーを計算します。
- サーマルセンサは、入射された光パワーに比例した電圧を送ります。 測定されたセンサの出力電圧とその感度特性に基づいて、コンソールは入射した光パワーを計算します。
- エネルギーセンサは焦電効果に基づいています。 したがって、エネルギーセンサは、パルスエネルギに比例したピーク電圧を送ります。 エネルギーセンサが認識されると、コンソールはピーク電圧ディテクタを活用し、センサの感度特性からパルスエネルギが計算されます。
センサはセンサが出力する電流や電圧を表示する機能も備えています。 または、測定された電流や電圧をアナログ出力で得ることもできます。

(posted 2020-07-09 08:41:26.2) Is it possible to get sensor calibration data at 785 nm? MKiess
(posted 2020-07-10 08:29:39.0) This is a response from Michael at Thorlabs. Each S120VC is individually calibrated before delivery. Therefore the values are slightly different for each sensor. The typical value for the responsivity of the S120VC at 785nm is 35.69mA/W. I have contacted you directly to discuss the exact details for your sensor. li bo

(posted 2020-06-17 10:26:09.0) This is a response from Wolfgang at Thorlabs. Thank you very much for your inquiry.
The question is how integrating sphere sensors like the S142C can be cleaned. The housing may be cleaned by wiping with a soft damp cloth. The integrating sphere inner surface however cannot be cleaned and should not be touched. You can gently blow off any debris using compressed air. If this does not remove all the dirt or dust in the sphere, the sphere will probably need to be exchanged so you would need to send the sensor in for a repair.
Our Tech Support team in China will reach out to you directly. 達也 真藤

(posted 2020-02-25 10:34:47.983) Hi,
I'm using the S130C to measure the power of a beam, either collimated, divergent or focused. Is it normal to have different power values depending on whether the beam covers a large fraction of the detector's surface (case of collimated beam) or covers a small surface (focused beam)?
Thank you for your help
Best nreusch
(posted 2020-02-27 09:02:08.0) This is a response from Nicola at Thorlabs. Thank you very much for your feedback! S130C comes with a Si photodiode. Photodiodes in general are sensitive to the angle of incidence. So for focused and divergent beams, you will always have parts of the beam that will not hit the sensor at a right angle, which will affect the measurement. Photodiode sensors will also not show a completely uniform response over their active area. Therefore, the specified measurement uncertainty is only valid for beam diameters larger than 1 mm. You should also take care to not overfill the sensor with a divergent beam. We will contact you directly to discuss your specific application in more detail. Matthew Kirchner
(posted 2019-11-25 13:24:07.727) Hi, does the S142C correct for temperature dependence of the Si photodiode responsivity? dpossin
(posted 2019-11-27 08:43:20.0) Dear Customer,
Thank you for your feedback. The S142C does not compensate temperature effects of the sensor automatically. However it is possible to compensate
the temperature dependent dark current with our powermeter consoles. I am reaching out to you to provide further information on that. user
(posted 2019-11-15 12:57:48.94) Dear Thorlabs,
We are considering ordering one of your products to measure the average power of a scanned pulsed laser, that reaches an aperture of a few mm, with the following parameters:
» Beam width: 1 mm
» Wavelength: 1,5 micron
» Pulse energy: 1 micro-Joule
» Pulse duration: 1 nW
The pulse train incident on the opening depends on its diameter as well as the scanning parameters:
» Repetition frequency: minimum 10 Hz (frame rate); maximum 1MHz (pulse repetition rate)
» Average power on aperture: typical 10 mW; minimum 10 micro-W; maximum 1 W (static beam).
Which kind of power meter do you recommend for the described application: a photo-diode/integrating sphere or a thermopile?
Sincerely,
Flávio Ferreira

(posted 2019-11-18 06:12:44.0) This is a response from Michael at Thorlabs. Thank you for the inquiry. Depending on the pulse duration, repetition rate, laser power and the general conditions of your application, a thermal sensor or a photodiode sensor may be suitable for you. In order to be able to use this optimally, different conditions have to be fulfilled depending on the sensor type. Details can be found under the following link:

I contacted you directly to discuss further details and select the most suitable sensor together with you. Karim Elkhouly
(posted 2019-10-23 07:39:14.07) I am considering using an integrated sphere for calibrated EQE measurements of LEDs. I am wondering what is the fundamental difference between standard power meters like the S120VC and ones for integrating spheres. Especially that the minimum detectable power is much higher in the latter option. Can I use S120VC with integrating sphere for example ? MKiess
(posted 2019-10-28 11:09:54.0) This is a response from Michael at Thorlabs. Thank you for the inquiry. The radiation scattered in the integrating sphere is almost ideally diffuse over the specified spectrum. This allows on the one hand to measure a photometric standard and on the other hand to measure the power or the total radiation flux of different light sources, independent of beam uniformity, divergence, beam shape and entrance angle, making them excellent for use with fiber sources and off-axis free space sources.
Due to the diffusivity, the power range is also higher than that of the sensors with which the radiation is measured directly, such as the S120VC.

(posted 2019-07-12 15:15:12.757) S12X series photodiodes have a poorly modeled solidworks file, can you update the model to reflect the internal size and position of the photodiode. While the aperture is 9.5mm, the aperture appears to be 3.3mm from the photodiode based on PDF drawing. This means that when measuring divergent light, if the photodiode is not large enough to collect all the light passing through the 9.5mm aperture then the measurement will be wrong. A +-45 degree light passing through a 9.5mm aperture with detector at 3.3mm away from aperture will expand the minimum radius of the photodiode by 3.3mm to 16.1mm diameter. wskopalik
(posted 2019-07-23 10:33:46.0) This is a response from Wolfgang at Thorlabs. Thank you very much for your inquiry!
It is generally not recommended to measure strongly divergent beams with a S12X series sensor. One reason is - as you have mentioned - that it is difficult to make sure that all the light is collected by the photodiode. In addition, photodiodes also show a dependence of the responsivity with respect to the angle of incidence. So these sensors are not ideal.
For a divergent beam e.g. the sensors of the S14X series would be much more suitable. These have an integrating sphere which makes the collection of the light easier and which also ensures that the light is shining on the photodiode perpendicularly.
I will contact you directly regarding these sensors and the drawings. Andrey Kuznetsov

(posted 2019-02-04 10:51:28.0) This is a response from Wolfgang at Thorlabs. Thank you very much for your inquiry!
The ideal case for photodiode sensors is if the beam hits the photodiode and the filter perpendicularly. This is how the sensors are calibrated so the accuracy is the highest in this case. The responsivity of photodiodes as well as the attenuation of filters depend on the angle of incidence. This means that the displayed power readings will change if the angle of incidence is changed. Thermal power sensors are more suitable for applications in which the angle changes because they have much less dependence on the angle of incidence.
I will contact you directly to provide further assistance. user

We don't recommend to exchange the ND filter window on these sensors yourself because the calibration is only valid with the filter which was mounted during the calibration. There are slight differences from filter to filter. So if the filter needs to be exchanged, the sensor needs to be recalibrated after the exchange. This can only be done in our facilities.

The photodiode used in the S148C which can cover this spectral range only has an active area of 1 mm in diameter. So with our sensor designs this photodiode only works in an integrating sphere. E.g. for the S132C design, the active area would need to be 9.7 mm x 9.7 mm in size.

(posted 2017-07-27 10:06:08.0) This is a response from Wolfgang at Thorlabs. Thank you very much for your inquiry.
The sensor itself wouldn't be damaged in this temperature range. There are however two drawbacks regarding the measurement accuracy.
First, you would need to make sure that there is no condensation inside the integrating sphere of the S142C due to the temperature change. Condensation would change the reflectivity of the sphere surface and would therefore affect the measurement values.
Second, the responsivity of Silicon photodiodes is dependent on the temperature. The calibration of these sensors is made at room temperature so you will get the most accurate reading there. In your case the temperature changes over 100K which would certainly affect the accuracy. This effect is more pronounced from 1000nm to higher wavelengths.

顕微鏡用スライドパワーセンサーヘッドS170Cは、顕微鏡システム内の試料の光パワーを測定するシリコンフォトダイオードセンサです。このシリコンフォトダイオードは、10 nW～150 mWの光パワーで350 nm～1100 nmの波長を検出できます。76.0 mm x 25.2 mmのセンサーヘッドは、標準の顕微鏡用スライドと同じ設置面積で、多くの標準的な正立および倒立顕微鏡にお使いいただけます。
このフォトダイオードの検出部は18 mm x 18 mmで、封止された筐体に収納されており、前面には光学濃度(OD)1.5のNDフィルタが付いています。NDフィルタ周辺には標準の顕微鏡のカバースリップのサイズに対応する20 mm x 20 mmの範囲で段差が付いています。液浸材(水、グリセロール、油など)はこの中(NDフィルタの上)に直接つけることができます。または、クリーニングを容易にするために最初にカバースリップを挿入することもできます。フォトダイオードとNDフィルタの間の隙間は、高開口数(NA)の油浸または水浸対物レンズを使用する際に大幅な測定誤差が発生するのを防ぐために、屈折率マッチングジェルで埋められています。
センサ筐体の背面には、検出部でのビームのアライメントと集光を補助するためのグリッドがレーザ刻印されています。正立顕微鏡では、このグリッドを使用してビームのアライメントを行った後、スライドを反転させ、センサを対物レンズに向けてパワーを測定します。倒立顕微鏡では、透過照明を照らしてセンサ筐体のグリッドとビームをアライメントし、センサが対物レンズの前中央に来るようにします。もしくは、NDフィルタの拡散面を集光面として使用することもできます。
各センサはNISTまたはPTBトレーサブル校正データとともに発送いたします。ここに含まれるデータは、各センサのテストに使用するフォトダイオードの校正証明書のデータと同じです。センサの仕様とNISTおよびPTBトレーサブルな校正データは、センサーコネクタの不揮発性メモリに保存されており、当社の最新世代のパワーメーターコンソールで読み出すことができます。当社では、精度および性能を確保するために年に1度の再校正をお勧めしています。再校正の詳細については当社にお問い合わせください。
仕様の詳細は、上の「仕様」タブをご参照ください。当社では、サーマルセンサ付きの顕微鏡用スライドセンサーヘッドもご用意しています。詳細はこちらからご覧いただけます。

ファイバ素線用アダプタS140-BFA(別売り)を取り付けたS142C

ファイバーアダプタS120-FC(付属)を取り付けたS142C
- ビーム形状や入射角に依存しない測定用
- 積分球が光パワー損失を最小限にする拡散器として機能
- 入射開口：Ø5 mm、Ø7 mm、Ø12 mm
- 取外し可能なファイバーアダプタS120-FC(FC/PCならびにFC/APC)が付属
- 対応するコネクタ付きファイバおよびファイバ素線用アダプタもご用意(下表参照)
これらの積分球フォトダイオードパワーセンサは、ビームの均一性、広がり角、形状および入射角に依存しないパワー測定に適しており、ファイバ光源や光軸から外れた空間伝搬する光源に適用できます。
当社の積分球は、可視～近赤外域の波長範囲に対応しています。 350～2500 nm用のセンサーヘッドにはZenith® PTFE製のØ25.4 mm(Ø1インチ)またはØ50.8 mm(Ø2インチ)の単球が使用され、入射開口部周辺での反射光を最小限に抑えるため、筐体は黒色になっています。 350～1100 nmの波長範囲で光を検出するセンサにはシリコン(Si)フォトダイオードが使用され、800～1700 nm、900～1650 nm、1200～2500 nmの波長範囲で光を検出するセンサにはInGaAsフォトダイオードが使用されています。
2.9～5.5 µm用の積分球S180Cには、金メッキ仕上げのØ20 mmの球が2個接続された状態で使用され、1つ目の球内に入射ポート、2つ目の球内にはMCT (HgCdTe)ディテクタ用のポートが付いています。 この球を2個使用する構成は、ディテクタを直接照明から効果的に保護しながら、内部の球の表面積を最小限に抑えることができるため、単球の設計に比べて装置の感度は向上します。 この設計は、別途遮蔽機構を使用せずにフォトダイオードを効果的に保護して、入射角や広がり角、ならびにビーム形状が測定結果に与える影響を低減します。
こちらでご紹介している積分球にはØ5 mm、Ø7 mm、Ø12 mmの大きな開口があり、正面の接続部はSM1外ネジ付きです。また、電磁波干渉を避けるためのシールドが強化され、高温警告センサが付いています。 センサの検出部が大きいため、付属のファイバーアダプタS120-FCにはFC/PCまたはFC/APCコネクタ付きファイバを接続することができます。 SM1外ネジ付きのアダプタはサイズ1(1 pt)のスクリュードライバを使用して取り外せるので、部品をウィンドウの近くに設置することができます。
各センサはNISTまたはPTBトレーサブル校正データとともに発送いたします。ここに含まれるデータは、各センサのテストに使用するフォトダイオードの校正証明書のデータと同じです。NISTおよびPTBトレーサブルな校正データは、センサーコネクタに保存されています。当社ではこちらのフォトダイオードセンサの再校正サービスをご提供しております。詳細については、当社までお問い合わせください。
