  • Ø12.7 mm(Ø1/2インチ)またはØ25.4 mm(Ø1インチ)をご用意
  • 1.2~8.0 μmのスペクトル範囲の赤外用途に使用可能
  • コーティング無し、もしくは2~5 µmで平均反射率< 1.25%のARコーティング付き

当社の単結晶シリコン(Si)高精度ウィンドウには、Ø12.7 mm(1/2インチ)とØ25.4 mm(1インチ)のサイズをご用意しています。 コーティング無し、もしくは両面に2~5 µmで平均反射率< 1.25%のARコーティングが付いたタイプからお選びいただけます(詳細は「グラフ」タブ参照)。シリコンは熱伝導性が高く密度が低いので、レーザーウィンドウに適しています。 しかし、9 µmで強い吸収帯があるので、CO2レーザの透過用途には適しません。

当社では、幅広いレーザおよび産業用途でお使いいただけるさまざまな基板材料の高精度ウィンドウを取り揃えています。ラインナップは右表からご覧いただけます。 また、当社では一般的に使用されているレーザ波長を中心とした特定の波長にARコーティングが施されたウェッジ付きシリコンウィンドウレーザーウィンドウ、またP偏光成分の反射を除去するブリュースターウィンドウもご用意しています。

The 'E coated' silicon windows (WG81050-E) come with a hazardous materials warning on the box (uncoated Silicon windows have no warning on the box). Are you able to say what the hazardous aspect of the E coating is?
blarowe  (posted 2024-11-07 09:35:04.0)
Thank you for contacting Thorlabs. I'm very sorry for the confusion here. It will actually be the silicon itself leading to that warning, and the uncoated windows should have similar warnings.

Could you please, send me information about the microroughness value? Is the Si window poished both sides?
jpolaris  (posted 2023-11-21 03:54:22.0)
Thank you for contacting Thorlabs. Yes, these Silicon windows are polished on both sides. Unfortunately, we have not characterized the microroughness of these Silicon windows at this time.
Felix  (posted 2023-10-16 11:01:03.933)
Hello, is the Silicon-Window a single-crystal? Whats the orientation and do you have precise measurements of the mechanical properties (elastic modulus, poisson ratio, density).
jdelia  (posted 2023-10-19 01:33:14.0)
Thank you for contacting Thorlabs. These Silicon Windows are high-resistance, Optical Grade, Czochralski Monocrystals. The OEM for this material uses both 111 and 100 orientations for the windows, however there is no flat side to mark the lattice orientation of the windows. You can find the mechanical properties of Silicon in our optical substrates tutorial here: https://www.thorlabs.com/newgrouppage9.cfm?objectgroup_id=6973&tabname=silicon.

Is there a reflection spectrum available for the uncoated Silicon?
cdolbashian  (posted 2022-09-26 04:43:24.0)
Thank you for reaching out to us Morken. While we do not have experimental data for the cumulative reflections for the uncoated Si windows, I think it is very feasible to use Fresnel reflection coefficient in conjunction with the Sellmeier equation in order to make a fair estimate of the reflection as a function of wavelength. I have contacted you directly with some suggestions regarding the execution of this calculation.

What is the maximum temperature for good transmission for your silicon windows?
cdolbashian  (posted 2022-02-09 05:06:49.0)
Thank you for reaching out to us at Thorlabs! At room temperature we would expect ~50% transmission. Based on some findings in literature, it seems like the transmission is nominally unaffected until temperatures exceeding 300C, and even at 300C the transmission only seems to drop to about 47%. I don't think we would recommend using them in excess of 300C as a general recommendation.

Do these exist with AR coarting at 1700 nm?
nbayconich  (posted 2019-05-13 01:00:36.0)
Thank you for contacting Thorlabs. We can provide custom coating options upon request, I will reach out to you directly to discuss our custom capabilities.

Hello, do you have a coating from 1.8 um to 3um? just like the silicon wedge provided by your company.
llamb  (posted 2018-03-30 01:53:32.0)
Hello, thank you for contacting Thorlabs. We do not have a standard silicon flat window with that anti-reflection coating, however we may be able to offer a custom product. If you are looking for the flat silicon window but with the 2- 5 um AR coating as on our silicon wedged windows, this particular coating run is not offered frequently so there would be a long lead time. I will reach out to you directly to discuss quoting.

Hello, what crystal growth process was used for this substrates, what purity does the material have, and how is the crystal oriented in respect to the window's optical axis?
jlow  (posted 2015-05-13 11:25:05.0)
Response from Jeremy at Thorlabs: The silicon windows we sell are only qualified by the optical properties we specified. The growth process, exact purity, and crystal orientation are not controlled explicitly.
a.wienke  (posted 2014-04-29 11:23:19.87)
Hi, Do you also have any transmission data below 2.0 µm? Down to 1.9 µm would be fine for me.
jlow  (posted 2014-04-29 05:08:28.0)
Response from Jeremy at Thorlabs: I will send you this information directly.
elharel  (posted 2014-02-11 17:32:46.72)
Is this amorphous or crystalline silicon?
jlow  (posted 2014-02-13 09:01:28.0)
Response from Jeremy at Thorlabs: These are monocrystalline Si.
tcohen  (posted 2012-05-09 16:09:00.0)
Update from Tim at Thorlabs: Unfortunately, our standard –C coating is typically used with materials of much lower index and would not yield positive results on a Silicon substrate. I have contacted you to continue this discussion.
tcohen  (posted 2012-05-09 14:12:00.0)
Response from Tim at Thorlabs: Thank you for your feedback! We do have 1550 nm AR coated windows utilizing different substrates. For this substrate, we may be able to offer a special with our standard –C coating. I will contact you to get more information on your application and to continue this conversation.

This product would be useful to me if it were AR coated for 1550 nm.
