Thorlabs索雷博 BBD1-E04 D形反射镜
特性
- 八种镀膜可选：
- 紫外增强铝膜：250 - 450 nm
- 有保护层的银膜：450 nm - 20 µm

- -E03宽带介质膜：750 - 1100 nm
- -E04宽带介质膜：1280 - 1600 nm
- Ø1/2英寸或Ø1英寸两种版本可选
- 小间距光束的理想选择
- 反射膜边缘距离直边边缘0.1 mm
这些D形(pickoff)反射镜，有多种不同的薄膜类型，能够分离间距很小的光束。反射膜边缘距离反射镜直边边缘的距离小于0.1 mm，因此，D形反射镜非常适合从两束间距很小的光束中选择一束光束。另外，从反射镜的直边边缘的背面切去了一块楔形，以防止那些没有被选取的光线挡住反射镜。我们也提供用于D形反射镜的固定式和可调式安装座。

- 这些规格在0°和45° AOI之间有效。
- 对于超快光学元件，激光诱导损伤阈值(LIDT)被定义为一定个数的脉冲后产生可见损伤的能量密度(单脉冲)。LIDT数值在超短脉冲范围是无法保证的。因此，它们只作为一个提供给客户的服务。请在曲线标签查看LIDT随入射脉冲数变化的曲线图。
- 光束的功率密度应该以W/cm为单位计算。关于为何线性功率密度对长脉冲和CW源提供最佳指标的解释，请参看损伤阈值标签。
