当社では、従来の拡散板にない多数の利点を備えるRPC Photonics社製のEngineered Diffuser™を販売しています。Engineered Diffuserは、さまざまなパターンの非ガウシアン強度分布を提供します。透過効率90 %の正方形、円形、ライン分布トップハット型の拡散板をご用意しています。正方形および円形バージョンには拡がり角20°と50°のオプションがあります。ライン分布バージョンの拡がりは0.4° x 100°です。すりガラス拡散板のような他の拡散板では、このように高度な光制御は不可能です。このEngineered DiffuserはØ0.5 mm以上のビームとのご使用いただけるよう設計されています。これよりも小さなビームは拡散板の前に拡大していただく必要があります。

Engineered Diffuserは、マウント無しとマウント付きバージョンからお選びいただけます。マウント付きØ25.4 mm拡散板は、刻印付きSM1ネジマウントに取り付けられています(ページ上部参照)。マウントは識別が簡単で拡散板を指紋や他の汚れから保護します。SM1ネジは特にØ25 mm~Ø25.4 mm(Ø1インチ)レンズチューブ30 mmケージシステムの構築に便利です。これらのマウント付き拡散板は、単品またはお得な5枚セットでお買い求めいただけます。

Engineered Diffuser テクノロジ
当社とRPC社のEngineered Diffuser™は、ビームプロファイルがしっかりと制御され、リソグラフィーシステムや、アウトドア照明、ディスプレイ、バックライト、ディスプレイ輝度の強化、プロジェクタースクリーンなどの幅広い用途で使用できます。

すりガラス、乳白ガラス、ホログラフィック素子などの(照明が)均一な拡散板は、開口全体に渡って連続して均一的な表面パターンが構成されているので、照明部の形ならびに強度プロファイルに関しては限定的な制御しかできず、入射光の利用効率が大きくできません。 また、ホログラフィック拡散板は、通常コヒーレント光を用いた単色用途に限られています。 一方、Engineered Diffuserは、個々に異なった形状で形成されたマイクロレンズユニットによって構成されているので、広帯域に対応し、光分布ならびにビームプロファイルを制御することが可能です。

拡散板を形成する各マイクロレンズユニットは、その表面プロファイルならびにアレイ中の位置を規定されます。 同時に、拡散板が入射ビームの強度プロファイルに変化があっても安定して拡散し、そして可視域ならびに赤外域でも確実に使用できるように、マイクロレンズ分布は、所望のビームを形成するための確率分布関数に従いランダム化されています。 マイクロレンズの分布はまた、出射光のゼロオーダの輝点ならびに回折によるアーティファクトを取り除くように設計されます。 このようにして、Engineered Diffuserは、ランダムかつ確定的な性質を持つことができるのです。

マスタ製造過程の略図

製造
マイクロレンズアレイのマスタはRPC Photonics社が開発したレーザ書込みシステムによって製造されます。 左図のように、この書込みシステムは、ラスタースキャンモードでpoint-by-pointに厚い層のフォトレジストを露光します。 レーザービームの強度を走査中に変調すると、フォトレジストへの露光度も変化します。 結果、上の2つのSEM像でみられるような深さのある表面が作り上げられました。

他の拡散板テクノロジとの比較
一般的に使われる拡散板にはプリズムガラスの集積バー、すりガラス、乳白ガラス、ホログラフィック拡散板、そして回折拡散板などがあります。 プリズムガラスの集積バーは、時々高性能なシステムに使用されることがありますが、高価でスペースを占領してしまう大きさとなっております。 すりガラスならびに乳白ガラスは、すべての方向において光を均等に散乱しますが、光制御の性能は限定的です。 また、このようなシンプルな拡散板における透過効率は一般的に低くなっております。 ホログラフィック拡散板は、これらの拡散板よりも優れた性能を持ちますが、ガウシアンと同様の強度プロファイルと円形または楕円形のパターンしか作ることができません。 一般的なビーム形成の性能としては、回折素子が入射ビームを任意の形に形成することができます。 しかし、狭い拡散角に限定され、波長には非常に敏感で、入射ビームと同一線上にあるゼロオーダの輝点を失くすことができません。

対照的に、Engineered Diffuserは、高い透過効率に加え、拡散光の発散角、空間分布、ならびに強度プロファイルを制御することができるのです。

手順
試験には488 nm、637 nm、785 nmならびに1064 nmの4波長を選びました。データの取得には右の試験装置を用いました(写真の下のリンクからこのセットアップのすべての部品がご覧いただけます)。 光路はブレッドボード表面から約35 cmの高さに設定し、ファイバ出力光源からの光は、その光源波長にできるだけ近い設計波長のトリプレットコリメータでコリメートしました。自由空間においてビームを1種類のEngineered Diffuserに入射します。Engineered Diffuserから出射された拡散プロファイルの光は、レンズチューブSM05L20取り付けられた平凸レンズLA1304で分離され、集光されます。信号はフォトダイオードSM05PD1Aにより0.5°毎にサンプリングされます。このアセンブリはレールXT34-500の端に取り付けられています。レールの反対側は回転ステージNR360Sに取り付けられ、その回転ステージの中心は試験対象のEngineered Diffuserに一致するように配置されています。そのためディテクタとレンズアセンブリは右下の図のようにビームプロファイルの中心を掃引し、出射角に対して規格化された強度をプロットできます。Engineered Diffuserとディテクタ間の距離は約43 cmです。出射角はEngineered Diffuserが光路に設置されていないときの光軸に対して定義しています。周辺光の影響を軽減するために、半導体レーザの駆動電流を1 kHzの正弦波で変調し、信号はロックインアップを用いて検出しています。セットアップの制御とデータ取得には、LabVIEWでプログラムを作成して使用しました。

試験についての制約
型番毎に1つの製品のみを試験していますa。試験は除振装置のないブレッドボードPBG11113b上で行なったため、安定性に影響がでた可能性があります。拡散形状の中心部のみを計測したため、正方形プロファイルの隅などを含め、中心部以外の場所では一致しない場合があります。

結果
拡散ビームプロファイルの波長による不一致は、プロファイルの中心部では僅かであることが判明しました。上記左側のグラフは、生成されるビームプロファイルを理論的に推定したものです。右側では理論モデルを検証するために様々な波長で試験したデータをまとめています。

Hi! Would you suggest 'Engineered Diffusers' to convert a white light source of near-Gaussian profile to flat-top profile? If not, is there any particular model you would suggest for the same? (we could use Apodizing reflective ND filters, but the output profile to be converted may not be an ideal Gaussian profile. Or will this do the job regardless of the above fact?) thanks!
YLohia  (posted 2019-10-21 12:15:22.0)
Hello, thank you for contacting Thorlabs. The engineered diffusers can be used with broadband sources such as LEDs. Please note that it is very important to have a well collimated input beam, otherwise the divergence from the source will completely wash out the effects of the diffuser.

Hi! I have twe questions about line pattern diffuser. 1. How can I align the diffused line pattern with my sample? 2. Is it effective to use two diffusers for more wider and uniform pattern?
nbayconich  (posted 2019-09-27 03:06:02.0)
Thank you for contacting Thorlabs. The alignment procedure can be very application dependent, I would recommend possibly using a rotation mount to hold this diffuser so you can control the angle of the line pattern. In terms of using a second diffuser this wouldn't necessarily improve your pattern uniformity. If needed you can collimate the pattern by placing a lens after the diffuser. I will reach out to you directly to discuss your application.

Hi! We plan to use these diffusers with a collimated (2W 830nm) laser diode. Do you know their damage threshold? We can adjust a bit the beam diameter, but we are not able to change it a lot. The documentation and the feedbacks talk about "low-power applications", without specified limit. Could you precise a bit more? (in terms of power density for example) Thanks a lot.
YLohia  (posted 2019-09-25 10:01:36.0)
Hello, our engineered diffusers have not been formally tested for laser damage. However, distortion from heat occurs at ~ 99°C. These are not intended to be used with high power lasers. If you're looking to convert a Gaussian intensity profile to a flat-top profile, our apodizing filters such as the NDY10B could be something to look into. Unfortunately, we have not yet performed intensive damage threshold testing on these optics. That being said, these were designed for low-power applications so it would be best if you are able to use the maximum possible beam diameter for a lower power density.

I have a inquiry for these products (engineered diffusers). If polarized laser pass through this diffuser, the polarization state preserves? Or become unpolarzed light? I look forward to your answer. Thank you. Best regards
nbayconich  (posted 2019-09-06 09:06:29.0)
Thank you for contacting Thorlabs. These diffusers should not rotate your polarization state and there will be no polarization scrambling caused from these engineered diffusers. There may be increased Fresnel reflection loss depending on the input polarization and orientation. A Techsupport representative will reach out to you directly to discuss your application.

I've noticed inhomogenetity in the way ED1-S20 affects my polarization. There is one spot on the diffuser which rotates the polarization from horizontal to vertical (the diffused square is oriented horizontally too, not diamond). Is this inhomogenetity expected or is it a defect? (if I buy another one, am I likely to have the same problem?)

Good Evening, I have a question about these diffuser : if I use a collimated laser light (CW @1053nm), the output light will diverge with a known angle (20° or 50°): will we able to collimate the output beam with a lens?
nbayconich  (posted 2019-02-05 08:30:45.0)
Thank you for contacting Thorlabs. After your collimated source passes through the engineered diffuser, your source can no longer be considered a single point source therefore not possible to perfectly collimate. A lens can be used after the diffuser to help reduce the amount divergence created by the diffuser however the beam size will still diverge as a function of distance and the intensity distribution will not maintain a perfectly flat top profile. A high NA lens like a condenser asphere can be used for example.

The specifics of the damage would depend on the peak power, pulse width, and rep rate of your source. These are not intended to be used with high power lasers. If you're looking to convert a Gaussian intensity profile to a flat-top profile, our apodizing filters such as the NDY10B could be something to look into.

Hello Marjin, thank you for contacting Thorlabs. Unfortunately, we have not yet performed intensive damage threshold testing on these optics. That being said, these were designed for low-power applications so it would be best if you are able to use the maximum possible beam diameter for a lower power density.

What is the fringe visibility? Do you have a zoomed in image of the pattern? Will the diffuser work with a non-collimated beam?
nbayconich  (posted 2018-10-12 09:50:22.0)
Thank you for contacting Thorlabs. The fringe or speckle pattern will depend on the coherence length of the source being used, If the laser has good spatial coherence the speckle will be noticeable and the contrast will be high. The input beam does not need to be Gaussian or circular shape to produce a square output and a slightly diverging source can be used as well however to achieve the best results the source must be collimated to avoid sharp features appearing from the diffuser's output. I will reach out to you directly to discuss your application and show you a few examples of the square pattern engineered diffusers output image.

Hi, I use ED1-C20-MD with 515nm picosecond with 10W/cm2. Input laser is collimated but due to long travel range speckles are serious. After passing the diffuser, many small grit-shaped circles appear. How to get better putput? Thank you Yayao
nbayconich  (posted 2018-10-12 10:32:29.0)
Thank you for contacting Thorlabs. If the laser source has good spatial coherence then the speckle will be noticeable and the contrast will be high. Users of diffusers must work out a method for speckle mitigation which would include aperture averaging or some other type of averaging such as motion over time with finite integration. One such example is to rotate the diffuser in use. Alternatively lower coherence sources such as LED or white light will show no speckle.

YLohia  (posted 2018-06-14 09:32:45.0)
Hello, I have sent you the curve via email. We do not recommend this diffuser for such high power applications.
user  (posted 2018-05-18 09:40:14.25)
It would be helpful to know how the diffuser impacts the polarization of light. Typically ground glass diffusers scatter light with random polarization. These engineered diffusers probably don't change the polarization, but it would be useful for the customer to know the polarization performance.
YLohia  (posted 2018-05-23 11:22:12.0)
Although your light does stay polarized, the actual state of polarization will change based on the input polarization of the light, as well as the location of the beam on the optic. For example, the magnitude of this change will be less if the polarization state is in line with the corners of the square diffuser. If your original polarization state is parallel to either side of the square, however, you will see a large amount of circularization.

Can you please provide the transmission curve for this diffuser from 350-650 nm. I would imagine the plastic will start to absorb somewhere in the UV, but it would be helpful to know where exactly that takes place.
YLohia  (posted 2018-03-30 12:15:55.0)
Response from Yashasvi at Thorlabs USA: Hello, thank you for contacting Thorlabs. You are correct, these will start absorbing light in the UV region, starting roughly ~320-350nm. Please note that we don't recommend using these for <400nm since there is some variation in the transmission below that wavelength from lot to lot. I will reach out to you directly with a typical transmission plot.

nbayconich  (posted 2017-10-16 12:21:10.0)
Thank you for contacting Thorlabs. The transmission of this material has little polarization dependence. There may be increased Fresnel reflection loss depending on the input polarization and orientation. For optimum performance align P polarization with the large diffusion axis in this case. There will be no polarization scrambling caused from these engineered diffusers.

nbayconich  (posted 2017-06-08 09:46:08.0)
Thank you for contacting Thorlabs. Once your coherent source passes through these diffusers it will no longer be coherent. Diffusers scatter light at different angles essentially eliminating and coherence of your source. This will not allow distinct modes to be diffracted from a grating. A techsupport representative will reach out to you directly with more information.

The specs simply state that the transmission is 90%. Similarly the chromatic dependence is normalized per trace. Can you please send me more detailed information about the transmission as a function of wavelength? I would like to know, for example, when changing the source wavelength from 500 nm to 700 nm, how much light will be lost or gained? Similarly you could post the integrated power. The easiest way to measure this is to use an integrating sphere to capture the light after the diffuser, connect a calibrated power meter to the output port of the integrating sphere, and use a calibrated source to measure this information. I hope you could provide this information, it will be very helpful. Thanks very much and I look forward to hearing back from you, Ron

Response from Bweh at Thorlabs USA: The engineered diffusers will not work the same. Unlike the pi-shaper, the output from the engineered diffusers will not be collimated but will have a fixed divergence. Regarding the interference fringes, we have not tested this. However, what you would likely observe is a degraded fringe visibility.

besembeson  (posted 2014-10-30 04:07:38.0)
Response from Bweh at Thorlabs USA: The angular spread that is specified for the engineered diffusers assumes a collimated input which is what is recommended. You can use a divergent source but the output divergence will be increased by a factor dependent on the divergence of the source. As an example, for a 0.22 NA fiber (~25 deg divergence), with the ED1-S20, the output divergence will increase by a factor of about 2.25 the engineered divergence angle specification.
