6 mmの光学スペーサSM1S6Mを用いてミラーマウントKM100に取り付けられたビームスプリッタ(低価格版)EBP1。

当社の低価格ビームスプリッタは、片面のみに酸化物のコーティングが付いていて、入射角45°の無偏光の光を入射した場合、可視スペクトル(450~650 nm)で50:50または30:70の分岐比となるように設計されています。これらの低価格ビームスプリッタは、裏面にコーティングが付いていないので、フレネル反射により反射光に干渉効果をもたらす可能性があります。この干渉効果に敏感な用途では、ビームスプリッターキューブのご使用をお勧めします。

下のグラフにはこの低価格可視光ビームスプリッタの反射率データが示されています。400~2300 nmをカバーする広範囲のプロット図は「グラフ」タブに掲載されています。

このビームスプリッタの厚さはわずか1 mmなので、止めネジ(セットスクリュ)を使用する光学マウントに取り付けると大きな応力が加わります。光学スペーサをお使いいただくと、光学素子に損傷を与えることなく止めネジを締め付けられる堅牢で広い取付け面を確保できます。

Hi Is there any product that can combine tow identical (same wavelengths) beam? Best Regard Mahdi
tfrisch  (posted 2017-05-03 11:54:24.0)
Hello, thank you for contacting Thorlabs. I will reach out to you about your application and whether the beams are coherent and whether constructive interference could be used. However, there is not an optic that can transmit fully in one direction and reflect fully from the other direction at the same wavelength.
yusefzadib  (posted 2017-05-03 15:39:53.327)
Hi What will happen If the beam is applied to the non-coated side? Is it still divides beam at ratio of 50 to 50? I had to apply beam to non-coated side. Best Regards Mahdi
tfrisch  (posted 2017-05-03 11:42:49.0)
Hello, thank you for contacting Thorlabs. I will reach out to you directly, but the biggest impact will be that the ghost beams will contain slightly more power if the beamsplitter is used in reverse. Applications where light passes both directions through a beam splitter are common.

Shining a solid state diode pulsed laser straight through one of the EBS2 beamsplitters caused a banding effect as seen here - http://imgur.com/a/sLW8m Is this caused by the material of the splitter itself, and would it be resolved if, for example, a beamsplitter cube was used instead? Thanks.
tfrisch  (posted 2016-11-29 01:24:48.0)
Hello, thank you for including that image. It looks like an interference effect due to multiple surface reflections off of the uncoated back surface. A cube beam splitter would help mitigate these interference effects.

The splitter ratio of EBP2 is 30:70 (R:T). Do you have a Beam Splitter with 70:30 (R:T) splitter ratio?

I am looking for the old "half-silvered mirror" metallized beam-splitter for use with quadrature interferometry. A protective coating over the metallization would be welcome and parallel surfaces (no wedge) are needed. I also need a dielectric reflection from the back, but I can generate that with plain glass if all of yours are AR coated. Most of your products obviously will not work, but others don't seem to say explicitly whether they utilize the metallization layer that I need. Do you, in fact, offer metallized beam-splitters? If so, what are some of their model numbers (1 inch optics preferred).
besembeson  (posted 2016-02-01 10:28:06.0)
Response from Bweh at Thorlabs USA: We don't have such half-slivered mirrors as stock items for quadrature interferometry. We can add a dielectric coating as required and we can provide a custom solution based on your requirements. I will follow-up with you.

An option to buy these thin economy beamsplitters mounted in a thicker housing to make mounting into something like the KM100 easier (similar to how the pellicle beamsplitters are mounted in a protective ring) would be helpful. I've looked at the SM1AB1, but I think it would cut the clear aperture down quite a bit when using the beamsplitter at 45 degrees.
besembeson  (posted 2015-08-18 08:42:05.0)
Response from Bweh at Thorlabs USA: We do have optics spacers (https://www.thorlabs.com/newgrouppage9.cfm?objectgroup_ID=4085) that you can use in this case. The optic is placed into the KM100 followed by a spacer and the nylon-tipped setscrew locks to the spacer.

What is the specification for the surface figure (e.g. lambda/4) for these beamsplitters? I see the spec for scratch/dig, but not the wavefront flatness. Thanks!
besembeson  (posted 2015-04-30 02:50:25.0)
Response from Bweh at Thorlabs USA: These would typically be 2 lambda (peak to valley).
zhangzyster  (posted 2015-02-21 23:09:58.47)
Hi, do you offer other size options? I need this half/half splitter about 100mm*150mm in size.
besembeson  (posted 2015-02-26 04:13:05.0)
Response from Bweh at Thorlabs USA: We can provide custom versions of this beamsplitter. I will followup with you by email for quotation.

Hello, I have 2 questions concerning the economic beam splitters (I am more interested in the EBP version): - Do they work under normal incidence? - In this condition, they should be insensitive to polarisation, right?
jlow  (posted 2014-01-15 08:39:28.0)
Response from Jeremy at Thorlabs: The beamsplitter is meant to be used with 45° angle of incidence (AOI). At small AOI, the beam splitting ratio will change significantly and the spectral response will not be as flat in the visible range.

what's the Damage Threshold of economic beamspliter EBS2 and EBP2?
tcohen  (posted 2013-08-08 15:32:00.0)
Response from Tim at Thorlabs: At this time we have a conservative theoretical value of 1W/cm^2. We are continuing to increase our knowledge-base on damage thresholds for optics, but in the meantime if power handling is a concern, we do have other higher power beamsplitters. We will contact you to discuss your requirements.

the % reflection scale of your graph doesnt make sense, it is backwards
sharrell  (posted 2013-05-02 11:47:00.0)
Response from Sean at Thorlabs: Thank you for pointing out that our graph was confusing. The data was correct-- there were separate lines for reflection and transmission. I made new graphs for this page so that each type of beamsplitter has it's own plot; I hope that this makes the data easier to understand.
Greg  (posted 2010-04-29 09:36:14.0)
A response from Greg at Thorlabs to wwarger: We now have a graph from 400 nm to 2300 nm on the Overview tab. Data for this graph can be downloaded by clicking on it.
Adam  (posted 2010-04-28 12:11:46.0)
A response from Adam at Thorlabs to wwarger: We are working on getting the data for the EBS1 at this range as well. We will post the data on the web as soon as we get the appropriate data. I will send you the data we have on the EBP1 directly.
wwarger  (posted 2010-04-28 10:16:44.0)
It would be extremely helpful if the previously requested spec from 1064 - 2000 nm was posted on the website.
apalmentieri  (posted 2010-02-02 14:43:57.0)
A response form Adam at Thorlabs to Nick: I am currently working on getting you a scan of the EBP1 that will provide you with the data you are looking for. I will send this to you via your email address.

Hello, Can you tell me what its T/R would be from 1064 to 2000 nm? Thank you, Nick
