当社の広帯域誘電体凹面ミラーは、光収集、イメージングおよび集光の用途に設計されています。 この反射光学素子では、色収差なく集光できるため、広帯域光源に特に適しています。633 nmにおける表面イレギュラリティは小さく、優れた画質をご提供します。

こちらのページでご紹介しているミラーはすべて当社の精密キネマティックミラーマウントを使用した取付けが可能です。

当社では、反射率は低くなりますが、より広い波長範囲で使用できる金属凹面ミラーもご用意しています。 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。

Dear Thorlabs, I would like to ask about the dispersion size of the mirror CM508-200-E03.Thank you.

Dear Thorlabs Team, I would like to ask about the concave mirror with dielectric coating for 1064 nm wavelength, with RoC = - 1m, and back side polished. Would you be able to provide such substrate? If is it would be a possibility what would be the lead time and the cost. Thank you, Ada

Hello Ada, custom items can be requested by clicking on the "Request Quote" button above or by emailing techsales@thorlabs.com. We will discuss the possibility of offering this.

Dear Thorlabs, I am interested in purchasing one of the dielectric concave mirrors. But I am curious whether the backside of the mirror is polished or not. I want to use it as a laser output coupler, so the backside should be polished.

Hello, thank you for contacting Thorlabs. These are not backside polished. Custom backside polished mirrors and other optics can be requested by emailing techsupport@thorlabs.com.

hi: For CM254-050-E03, is it possible to order the mirror that the backside is polished? We would like to use two of this mirror to make a fabry-Perot interferometer.

Hello, thank you for contacting Thorlabs. Custom backside polished mirrors and other optics can be requested by emailing techsupport@thorlabs.com. I have reached out to you directly regarding this.

I needed two of these mirrors for a mini-project. The label on the box was correct but there were CM508-1000-E03 mirrors inside! I wonder why you are using a focal length for curved mirrors while using a radius of curvature is more common. I guess your staff might have thought that 1000 indicates R=1000 mm so it was the correct optic to go in the box. I hope you consider to use the radius of curvature for curved mirrors to avoid such mistakes or at least ask your staff to put correct optics in the boxes. Thank you.

Hello, thank you for your feedback and our sincere apologies for the packaging error. I have reached out to you directly to gather order information to set up inspected replacements for these mirrors.

I am interested in obtaining E03 coated concave mirrors that are backside polished. Is this possible? I would also like to know the approximate reflectivity of E03 coating at 632 nm (yes, I know that's not the design wavelength of the coating). Thank you
YLohia  (posted 2019-08-06 02:10:41.0)
Hello, thank you for contacting Thorlabs. The EO3 mirror coating is expected to have a reflectivity of ~92.8% at 632nm at 8deg AOI. The -s and -p reflectivities are ~99% and 97% respectively at 45deg AOI. Note that this is not a formal spec since it is outside of the designed coating range. Please email techsupport@thorlabs.com for custom item quotes. We will reach out to you directly to discuss the possibility of offering this.

凹面ミラーセレクションガイド

当社では凹面ミラーとして金属コーティング付きと誘電体コーティング付きをご用意しております。金属コーティングミラーは広い波長域で比較的高い反射率(90~95%)を有します。誘電体コーティングミラーは、さらに高い反射率(>99%)を有しますが、波長範囲は金属コーティングミラーと比べて狭くなっております。凹面ミラーのコーティングの種類につきましては、右の表をご覧ください。直径がØ12.7 mm (1/2インチ)~Ø75 mmの範囲の光学素子については、全種類のコーティングからお選びいただけます。金属コーティングミラーは焦点距離9.5~1000 mm、誘電体コーティングミラーは焦点距離12~1000 mmの製品をご用意しております。

下のグラフは金属コーティング、誘電体コーティング、ならびに結晶コーティングの凹面ミラーの反射特性を示しています。金属コーティングミラーグラフのコーティング毎のミラーのラインナップについては、グラフの線をクリックするか、凡例のコーティング名をクリックしてご覧ください。金属コーティングと誘電体コーティングミラーのグラフでは、入射角は8°または6°となっています。結晶コーティングミラーのグラフでの入射角は0°です。
