Thorlabs索雷博 PFE05-P01 椭圆反射镜

PFE05-P01 - 椭圆反射镜，有保护层的银膜，1/2英寸，450 nm - 20 µm

45°时为1/2英寸、1英寸或2英寸圆形孔径
金属膜或宽带介质膜
- 宽带介质膜：400 - 750 nm(-E02)或750 - 1100 nm(-E03)膜
- 金属膜：有保护层的铝膜、有保护层的银膜、超快增强型银膜或有保护层的金膜
平面反射镜，紫外熔融石英基底

Thorlabs的椭圆反射镜在椭圆紫外熔融石英基底或椭圆熔融石英基底上具有镀膜面。当反射镜绕椭圆短轴旋转45°时，所得的通光孔径为圆形，如图1.3所示。

安装选项
我们建议使用我们的45°固定式椭圆反射镜安装座或椭圆反射镜调整架以安装这些反射镜。我们的45°固定式安装座兼容1英寸或2英寸椭圆反射镜。它们可接杆安装，或固定在无螺纹的标准反射镜调整架内。图1.1所示的实例是椭圆反射镜安装在H45E2 45°椭圆光学元件安装座中。

我们的光学调整架兼容1/2英寸、1英寸或2英寸椭圆反射镜。这些调整架还兼容我们的笼式系统和SM系列透镜套筒，从而可以使用多种光机械结构标准。本页右上方的图为1英寸有保护层的金膜椭圆反射镜安装在KCB1E(/M)直角光学调整架中。
