特長
- λ = 200 nm～6 μmで透過率≥ 94%
- 波長120 nmにおいても、透過率＞50%
- Ø12.7 mm(Ø1/2インチ)およびØ25.4 mm(Ø1インチ)バージョンから選択可能
フッ化マグネシウム(MgF2)製のウィンドウはØ12.7 mm(Ø1/2インチ)、Ø25.4 mm(Ø1インチ)のサイズが用意されています。これらは、深紫外域から中赤外域で高い透過率を有しています。このウィンドウは非常に耐久性があり収差を最小に抑えることができます。フッ化マグネシウム(MgF2)ウィンドウは光軸が結晶のC軸に平行になるようにカットされており、複屈折が最小に抑えられています。
フッ化マグネシウム(MgF2) ウィンドウは真空UV域範囲を含む深紫外(UV)域にお使いいただけます。120 nmでも＞50%の透過率が得られるので、エキシマレーザ、また 121 nmで水素ライマンα線適用の製品とのご使用に適しています。UVA、UVB、可視域または赤外域(200～1000 nm)では、約94%の透過率、波長範囲1～6 µmでは約95%の透過率を示します。

(posted 2024-08-29 10:44:48.903) Hi,
Looking at this product from profile, there seems to be two phases or material finishes.
It is supposed to be bulk uncoated material, so what is this ?
And is there a recommended side for incident light ?
Thanks,
Arnaud cdolbashian
(posted 2024-08-30 12:53:06.0) Thank you for reaching out to us with this inquiry Arnaud. These are cut and polished bulk material which are uncoated. I have contacted you do discuss any potential misunderstanding stemming from the presentation of these windows on our web page. Alexander Enders
(posted 2023-07-19 10:22:08.217) Hello,
I have a quick question: What is the orientation of the optical axis of your MgF2 windows? Perpendicular to the plane of the window to prevent birefringence?
Best

i like a WG61050 - Ø1" MgF2 Broadband Precision Window, coated to 1064 HR
also with PL//R =100mm CC
thanks YLohia
(posted 2021-08-27 02:46:42.0) Hello, custom optics can be requested by emailing techsales@thorlabs.com. We will discuss the possibility of offering this directly. Enrique Vasco
(posted 2020-10-03 15:11:52.777) Please, could you provide me with data on MgF2 window damage thresholds for 10 ns-pulsed UV laser, as the product description specifies that it is suitable for excimer laser and deep UV applications? Thankx YLohia
(posted 2020-10-07 02:30:18.0) Thank you for contacting Thorlabs. Unfortunately, we don't test or specify LIDT for bulk optics. Based on your beam parameters (266 nm, 100 mJ, 8 ns, 10 Hz, 3mm) and the literature available online, we expect the WG60530 to not sustain damage, but we cannot provide any guarantees for this at the moment. |
