当社の保護膜付き銀コーティング凹面ミラーは、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。これらの反射光学素子では、色収差を発生させることなく集光できるため、広帯域光源に特に適しています。
これらのミラーはN-BK7基板に銀コーティング、さらに表面にSiO2保護膜がコーティングされています。反射率の平均値は、450 nm～2 µmのスペクトル範囲では> 97%、2～20 µmのスペクトル範囲では> 95%となっています。780 nmに近い波長での用途では、保護膜付きアルミニウムより優れています。λ/4@633 nm の面精度で、優れた画質を提供します。
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。
450 nm～20 µmにわたる高い反射率のために、これらのミラーはフェムト秒パルスレーザでのご使用にも適しています。超短パルス用光学素子の全ラインナップは「超短パルス用光学素子」タブをご参照ください。
この光学素子の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の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注意ください。
取扱いについて
銀コーティング付きミラーは、環境や不適切な取り扱いによって損傷しやすいため、特にご注意いただく必要があります。指紋の付着、研磨性のある面との接触、高湿/高温の環境などにより、保護膜の効果が損なわれ、銀コーティングの酸化や劣化が起きやすくなります。 銀ミラーを取り扱う際は、通常の光学素子の取扱い方法に従ってください。 光学素子の表面に指の油分などが付着するのを防ぐために、Latex製手袋などの着用をお勧めします。こうした対策を講じたうえで、ミラー面やエッジには触れないようにご注意ください。 銀ミラーは、室温で、できるだけ湿度の低い場所で使用/保管を行ってください。ミラーなどの光学素子のクリーニング法については、「光学素子の取扱いについてのチュートリアル」をご参照ください。
下のグラフの網掛けの部分は、この光学素子をご使用になる際に推奨する波長範囲を示しています。製造ロットにより、特にこの帯域外(反射率が変動したり傾斜したりしている範囲)の反射率は、バラツキがある可能性がありますのでご注意ください。
フェムト秒パルスレーザ用ならびにピコ秒レーザ用光学素子を幅広くご用意しています。詳細は下表をご参照ください。

(posted 2023-05-03 10:21:51.43) Dear. service manager Hi, I'm a PhD student at Politecnico di Milano. I need information about the Damage Threshold of the mirror CM508-1000-P01. I appreciate any help you can provide. Best jdelia
(posted 2023-05-03 01:53:21.0) Thank you for contacting Thorlabs. Our specified damage threshold for our -P01 coated mirrors is as follows: 0.225 J/cm2 (800 nm, 99 fs, 1 kHz, Ø0.167 mm) and 1 J/cm2 (1064 nm, 10 ns, 10 Hz, Ø1.010 mm) for pulsed sources, as well as 500 W/cm (1.07 µm, Ø0.974 mm) and 1500 W/cm (10.6 µm, Ø0.339 mm) for CW sources. 任 骥
(posted 2020-10-20 01:37:00.387) what is the focal length tolerance(or euqvialently, radius of curvature tolerance) for concave mirrors? I'm intersted in 4 possible scenarios: f=150mm(diam.=1 ich), 200mm(diam.=1inch & 2inch) ,300mm(diam.>30mm)
Thanks in advance. YLohia
(posted 2020-10-20 11:24:45.0) Thank you for contacting Thorlabs. The radii of curvatures of these mirrors have a tolerance of +/- 0.2%. Hangchan Jo

Hi, I'm Hangchan, a Ph.D. student at Inha University in South Korea.
I need .ZMX files of the concave mirrors to design optical systems.
Although you provide some .ZMX files of the lens, I can't find concave mirrors' design files.
I look forward to being provided with what I need.
Best regards
Hangchan YLohia
(posted 2020-09-24 03:54:44.0) Hello Hangchan, thank you for contacting Thorlabs. What specific mirror are you looking for the Zemax files of? I had reached out to you at the time of your original posting, but I never heard back. If you still need this information, please email us at techsupport@thorlabs.com. benju
(posted 2019-02-23 06:18:51.807) It would be great if this one was offered with f = 300 mm as well. nbayconich
(posted 2019-02-26 11:03:46.0) Thank you for contacting Thorlabs. We can provide custom version of these mirrors upon request. I will reach out to you directly with more information about our custom capabilities. cbrideau
(posted 2016-09-20 12:36:25.863) Any chance of getting a 75mm silver mirror with a 250mm focal length? Is Ultrafast Protected Silver a possible coating option? If you can do this focal length please quote. jlow
(posted 2016-09-21 04:55:06.0) Response from Jeremy at Thorlabs: We will contact you directly about the quote. germantiunov
(posted 2015-08-20 10:18:29.973) Good day!
Do this mirror (CM750-075-P01) withstand laser beam with diameter 2 mm and power 700 W?
Thanks, German Tiunov jlow
(posted 2015-08-25 04:03:04.0) Response from Jeremy at Thorlabs: The damage threshold for the mirror is listed on the website as 1750 W/cm at 1.064µm (Ø0.044mm beam size) and 1500 W/cm at 10.6µm (Ø0.339mm beam size). 700W with Ø2mm beam size would equate to >3500W/cm which will damage the mirror. user
(posted 2013-03-04 10:23:18.16) specified for use 450-20um, but the graphs only show up to 2.6um sharrell
(posted 2013-03-05 17:08:00.0) A Response from Sean at Thorlabs: Thank you for your feedback. Our optics team is working on scanning these mirrors over a wider wavelength range and we will update our webpage with the data as soon as it is available. We do not have your email address, but if you wish to have the data emailed to you when it is available, please contact us via email at techsupport@thorlabs.com. |
