当社の保護膜付きアルミニウムコーティング凹面ミラーは、集光、イメージングなどの用途向けに設計されています。これらの反射用の光学素子では、集光時に色収差が生じないので、特に広帯域の光源での使用に適します。
これらのミラーの反射率の平均値は、450 nm~2 µmのスペクトル範囲では>90%で、2~20 µmのスペクトル範囲では>95%となっています。 この製品は基板がN-BK7で、アルミニウムコーティングと、さらに表面に保護を目的としたSiO2オーバーコーティングが施されています。 633 nmでの球面精度はλ/4で、優れた画像品質を提供します。 780 nmに近い波長での用途をお考えの場合は、この製品ではなく、当社の銀コーティング付きミラーまたはE03シリーズの誘電体ミラーの使用をお勧めします。
このページの全てのミラーは精密キネマティックミラーマウントに取り付けられます。
この光学素子でカスタム仕様をご希望の場合は当社にご相談ください。 また当社では、金属ミラーよりも高い反射率を実現する 誘電体凹面ミラーもご提供しておりますが、誘電体凹面ミラーの場合、対応する波長の帯域幅が狭くなる点にご留意ください。
下のグラフの網掛け部分は、このミラーの推奨使用範囲です。この帯域の外側(特に反射率のグラフにに変動や傾斜がみられる範囲)は品質管理の面で厳密に測定されたものではなく、ロット毎にバラつきがある可能性があります。

 (posted 2021-06-15 11:04:46.0) Hello, thank you for contacting Thorlabs. What type of a certificate are you looking for exactly? user
 (posted 2013-09-05 13:37:01.367) It would be great if more focal lengths were offered (e.g. 1000-5000 mm). Same for convex mirrors (500-5000). jlow
 (posted 2013-09-11 09:09:00.0) Response from Jeremy at Thorlabs: Thank you for your feedback. We will look into the possibility of offering more focal lengths. cdaly
 (posted 2013-01-25 17:32:17.833) Response from Chris at Thorlabs: Thank you for using the web feedback. Yes, we would be able to offer uncoated substrates for the concave mirrors. I will contact you directly to discuss your requirements. franxm
 (posted 2013-01-25 13:23:21.263) Would Thorlabs offer uncoated mirror substrates?
Thanks. sharrell
 (posted 2012-08-06 14:30:00.0) Response from Sean at Thorlabs: Thank you for your feedback. I am sorry that the mirror thickness is missing from our specs table. We are in the process of revising the way many of our optics specs are presented, and we have moved this page to the top of the list. We expect that an updated webpage will be available by the end of the week. In the meantime, the thickness is available on the pdf drawing available for each mirror by clicking on the red "Documents" icon next to each item number in the price box. user
 (posted 2012-08-04 18:57:10.0) The thickness data seems to be missing, it is important for me to have this data when picking an optic, please consider adding it. jjurado
 (posted 2011-02-18 17:15:00.0) Response from Javier at Thorlabs to Christian Roedel: Thank you for contacting us with your request. We can certainly offer our mirrors without the protective coating. We will contact you directly to get more details about your requirements. christian.roedel
 (posted 2011-02-17 12:15:17.0) I would like to use these mirrors for simple XUV applications. Is it possible to get them without a protection overcoat? A plain gold coating would be necessary for my application. acable
 (posted 2007-07-23 13:06:16.0) Overview text is not well written, for instance "insufficient anti-reflection coatings" is poorly worded, please rewrite the entire overview.
Having a plot that is the result of an actual measurement would lend confidence to the reader, where the highly smoothed spectral curve does not.
Had to try to submit twice, i couldn't tell the difference between "15" and "I5" for the security code, at least that is my guess as to why. |
Click on a particular graphed line or the corresponding name in the legend to view concave mirrors with that coating option.
Metallic-Coated Concave Mirrors are available in UV Enhanced Aluminum, Aluminum, Silver, and Gold.
