このマウント無しの N-BK7 すりガラス拡散板は、ガウシアン状の拡散分布を必要とする幅広い用途でお使いいただけます。 すりガラス拡散板は、粒度が120、220、600、1500のいずれかの研磨剤で片面が研磨され、拡散面(すりガラス面)が形成されています。12.7 mm(1/2インチ)、25.4 mm(1インチ)、50.8 mm(2インチ)の円形の拡散板に加えて、100 mm x 100 mmの正方形の拡散板においては、全ての粒度で加工された製品を取り揃えています。

さらに高い透過率を実現するためにØ25.4 mm(Ø1インチ)の拡散板では、350~700 nmまたは650~1050 nmのARコーティング付きでご提供しています。 拡散板を取り付ける時には、拡散面(すりガラス面)を光源の反対側に向ける必要があります。

研磨された拡散板は、サンドブラスト拡散板より高い表面均一性があります。 様々な研磨剤が、細かい散乱から粗い散乱まで幅広い散乱を可能にします。 細かい研磨(1500グリットなど)では透過率が高くなります。粗い研磨(120グリットなど)では透過率が低くなりますが、拡散のパターンは広がります。 上のグラフではガラス拡散板の性能を比較しています。

透過率はデータの取得方法に影響されることにご注意ください。この測定では、積分球センサと分光器が共に用いられています。分光器では許容受光角度が小さいため、グリット値が小さくなり大きく分散した光を全て受光するのが困難になります。したがって、グリット値が低くなると透過率も低くなります。


双方向散乱分布関数(BSDF)のグラフ

ここに示すデータは、拡散板に向けてHeNeレーザ光を照射し、拡散板の周囲を受光器を回転させて角度分解散乱光(ARS)を測定することで取得しています。双方向散乱分布関数(BSDF)は、ARSを入射ビームと受光器の間の角度の余弦で除することで求められますが、これは光が拡散板を通過した際に発生する散乱の量を表します。これらのグラフのX軸は散乱された角度を示しています。そのため0°でスパイクが現れる場合がありますが、これは拡散されずに透過するビームを表しています。

コリメート済みLED光源構成例

右下の図の構成例では、LED光源の出力光をコリメートする拡散LEDコンデンサの一部に50.8 mm角、600グリットのすりガラス拡散板DG20-600を使用しています。当社では、構成例と同じような性能を有するコリメート済みのLED光源もご提供していますが、こちらでは教育用の教材などに適した自作ができるセットアップを例示しています。この構成例は、60 mmケージシステムを使って構築されています。当社の60 mmケージアセンブリは、ケージロッドで連結するケージシステム対応の部品から構成されています。各ケージ用部品は間隔60 mmのネジ穴が4つあり、様々な長さのØ6 mmの頑丈なスチール製ロッドを使用してケージシステムに組み込みます。こちらの構成では、長さ101.6 mmのロッドが使われています。 ケージシステムを構築することにより、ケージシステム内の光学部品が共通の光軸を持ち、正確な固定が可能となります。

SM1内ネジ付きマウント済み温白色LED MWWHL4を60 mmケージシステムに組み込むには、マウント済みLEDをケージプレートアダプタLCP02/M(30 mm-60 mm変換)に接続したレンズチューブカプラSM1T2を用います。次に、固定リングSM2RRを用いて60 mm ケージプレートLCP34/Mに取付けた50.8 mm角、600グリットのすりガラス拡散板へ光源を向けます。LED光を拡散し、Ø50.8 mm(Ø2インチ)平凸レンズLA1401でコリメート光となります。レンズにはコーティングが施されておらず、焦点距離は60.0 mmです。 レンズは60 mm ケージプレートLCP34/Mに取り付けます。

60 mmケージアセンブリ全体は、LCP34/Mの底面にあるM4ネジ穴を利用してポストTR75/M上に固定します。ポストはポストホルダPH75/Mと取付けベースBA2/Mでブレッドボードに固定します。

Query on grain size of DG20-600 Dear sir I was trying to understand better the specifications of your ground glass diffuser. While it is clear on the grind grit used for different part numbers, I am not able to deduce the approximate/average grain size of the diffuser structure of your parts. I would appreciate if you can update me on the approximate/average grain size for #600GRIT polished diffuser. thx yicheng

Thank you for reaching out to us with this inquiry! We do not spec particle size when we characterize these diffusers, but rather the scattering performance and grit size. I have contacted you directly to discuss your application.
shampy mansha  (posted 2023-10-10 12:00:35.403)
Hi, I was interested in knowing the relation between the grit size and surface roughness of the glass diffuser. Say we have grit size 600, then what is the mean height and the standard deviation of height of the "rough" surface of the glass diffuser? Is there a grit conversion chart where we can have these surface roughness values? Thank you.
jdelia  (posted 2023-10-13 12:23:06.0)
Thank you for contacting Thorlabs. We unfortunately do not have this information as we do not measure the specific size of the particles, and the standard we use is not always the same throughout the years. We characterize them by the grit # and the performance.

Hello, I wish to transmit a range of lights from a single large panel light, aiming for transmission at points between 5-95%. How does using a diffuser will be different from using a ND filter?
jgreschler  (posted 2023-04-14 03:04:19.0)
Thank you for reaching out to Thorlabs. The ground glass diffusers will serve two primary functions- incoming spectral light will be transmitted as diffuse, and the beam will leave with some amount of divergence. They do not work effectively to reduce the beam power. ND filters by comparison preserve spectral qualities and collimation, but cut down on power according to their OD specification.

Thank you for reaching out to Thorlabs. Additional specifications including damage threshold can be requested by contacting techsupport@thorlabs.com. In this case damage threshold is going to be highly dependent on your laser parameters. I have reached out to you directly to discuss this further.

Hi Thorlabs, In your description it said when positioning the diffusers, the grit-polished side should face away from the source. We wonder how we can tell which side is the grit-polished side of a diffuser like DG10-1500? Many thanks, Zihao
cdolbashian  (posted 2022-06-06 10:27:35.0)
Thank you for reaching out to us with this inquiry. While 1500 is the finest grit diffuser we offer here, determining the specular side is fairly straightforward. I would sat the easiest way was to tilt your diffuser such that you could see the reflection of a bright source, perhaps a room overhead light. On one side, you will see a clear crisp image from the specular reflection, while on the diffuse side, even though the grit is very fine, you will see a more blurry reflection. I have reached out to you directly with an additional suggestion.

Hi Thorlabs, We've recently bought the diffusers DG05-220 and DG05-1500. And we are planning to focus a laser beam onto one of the diffusers to make the scattering light field. The thing is we don't know if the laser beam after tightly focusing would burn the diffuser. Can you provide any information about that? Best, Zihao

Hi there, if I wish to collimate an LED, to then focus it, is it necessary to have a ground glass diffuser in between the two lenses?
YLohia  (posted 2021-07-15 11:03:26.0)
Hello, thank you for contacting Thorlabs. It is not necessary to use a ground glass diffuser in between, but we do strongly recommend it for a more homogeneous beam and to prevent an image of the LED emitter (square) from being projected to the focused spot.

We are using your diffusers as the front element of a target board to measure HEL beam profiles. I note you advise to orient the diffusive slide so the diffuse surface is on the back (down-beam). Was this the orientation used to obtain your published data for radiant intensity versus scattering angle? If we flip the slide to put the diffuse surface on the front side, will the scattering pattern be the same? Thanks for any insight!

James Griggs  (posted 2020-05-25 12:43:44.26)
Hi, I have two questions about how the power vs angle plots were measured. 1. What was the geometry of the diffuser and detector? Was the power measured along a plane perpendicular to the diffuser surface, or on a circle at constant radius from the incident spot? 2. Are the big discontinuities near 68 and 83 degrees real, or an artifact of the measurement geometry? Comment: Its surprising that the DG600 curve has a sharp peak, whereas the DG220 has a rounded peak. Most peaks are rounded at the maximum. Thanks for your responses, Jim Griggs
nbayconich  (posted 2020-06-02 05:34:59.0)
Thank you for your feedback, the power distribution was measured on a plane parallel to the surface of the diffuser. The discontinuities are artifacts during the measurement procedure. The fine grit sizes will create less diffusion in the output creating more well defined peaks than the coarse grit sizes.

In the plot of diffuser transmission vs output angle, why are the curves for DG-120 and DG-220 basically the same, and those for DG-600 and DG-1500 are also very similar? I would expect a more gradual transition between grit polishes.
MKiess  (posted 2020-01-24 07:50:24.0)
Thank you for contacting Thorlabs. The grit sizes are relatively close which can be seen from the transmission vs. wavelength graphs. We do not control the scattering profile of our diffusers, we ensure that the diffusers are ground to the particular grit size specified.

Dear Thorlabs pals, Could you kindly explain how can I compare the capability of the diffuser by only transmission? I bought one ground glass diffuser and the diffused phenomenon is not clear. Could you help us on this case? Thanks for your strongly support. Best regards, Roger Lo
llamb  (posted 2018-03-02 08:19:16.0)
Hello Roger, thank you for contacting Thorlabs. There will tend to be a higher transmission for the finer/higher grits, as the less diffusive surface will scatter less. I will reach out to you directly as well.
dennis.gardner  (posted 2017-12-05 11:01:03.527)
There are a few standards regarding grit size. Which standard is being used here? ISO/FEPA? CAMI?
nbayconich  (posted 2018-05-07 03:03:57.0)
While we do not specify grit standards, we use the CAMI standard when polishing diffusers in-house while inspecting diffusers received from external vendors to a similar standard.
akuznetsov  (posted 2017-09-07 12:27:08.297)
Would be good to have images of the diffuser showing how well different grits diffuse light for a point source for example, or an LED source preferably. The point is to figure out which grit will be suitable for application based on how well the diffuser homogenizes the light. The setup would require a camera with a lens looking directly at the diffuser with the light behind the diffuser, preferably in a coupled configuration. In fact would be good to have this type of image for all diffuser optics.

I have question concering ground diffusers: We would like to create some diffusive feedback to the laser (to study the impact of feedback on the laser performance). In our experiment, we have the laser then comes the diffuser (tilted by 30°) and after the diffuser the photodiode (the laser points diretely (through the diffuser) into the photodiode). Our questions: 1. We need just a bit of feedback (below 0.1%). 2. not absolute necessary, but an AR coating at 1512nm would be useful 3. Size: Could you make a window of 7.5mm diameter 4. What is the transmission of the glasses (we want to measure the laser power with a fotodiode on the other side of the diffuser. The transmission should be high (not too much disturbed by the diffuser)

Response from Tim at Thorlabs: We can provide a –C AR coating if desired as well as provide custom diameters. The amount you receive at your photodiode is dependent on the geometry of your setup as they will diffuse in an intensity distribution as shown in the graph on the “Overview” tab. We also have the total transmission available on the “Graphs” tab. We will contact you to discuss your setup directly.

This is probably a silly question, but which way round should I use the diffuser? i.e. Should my laser beam be hitting the shiny surface or the "frosted" surface first? I have already destroyed two holographic diffusers so I don't want to make another mistake...
tcohen  (posted 2012-04-03 10:23:00.0)
Response from Tim at Thorlabs: The setup in the “Application Idea” will produce a uniform but collimated beam from your LED. If uniformity is more of a concern than transmittance, using a lower grit diffuser will allow for more diffusion. Also, as an alternative we offer Engineered Diffusers at http://thorlabs.com/NewGroupPage9.cfm?ObjectGroup_ID=1660 which will greatly homogenize the input illumination. I have contacted you to further discuss the use of these diffusers in your application.

I have tested your dg20-600 and 1500 grit following your graph on trasmission. Surprisingly I have found no difference in trasmission between them (measured with a spectrofotometer), moreover the trasmission is very poor (about 40%). For comparison another glass diffuser that I have (but I do not know the grit) perform 80% trasmission and looks more coarse. I am wondering if your graph is correct, my suspect is that the scale is inverted and the 120 grit is the more trasmissive. Please let me know if this is the case

Alternatively, do you know of any commercially available diffusers that get their properties from bulk and not from surface treatment? With my best regards, Pascal Mauron
