产品系列说明

提供适用于 UV、可见光和 NIR 的无镀膜选件或有 BBAR 镀膜的选件
非常适用于成像应用
标准直径从 5mm 至 200
还提供1λ 或 λ/10 UV 熔融石英窗口片

TECHSPEC® λ/4 UV 熔融石英窗口片经过精心制造，其规格具有 40-20 的表面质量和 λ/4 的传输波前误差，因此非常适用于成像应用。这些窗口片采用 UV 熔融石英基片，在从紫外 (UV) 到可见光和近红外 (NIR) 的范围内能提供很高的透射率。有宽带增透 (BBAR) 膜的选件可最大限度减少反射损失，并提高透射率。TECHSPEC λ/4 UV 熔融石英窗口片用于光学成像应用和低功率至中功率的激光应用中，还可以用作保护性窗口片，尤其是在需要透射紫外线的应用中，更是如此。
