产品介绍
TECHSPEC® 氟化钙 (CaF2) 具有较低的折射率，在未镀膜的情况下可提供 200 - 7000 纳米的高透过率。 为了进一步提高透射率并减少背向反射，我们还提供了覆盖从紫外 (UV) 到中波红外 (MWIR)波段的各种增透镀膜。 由于氟化钙的块体具有高损伤阈值和低吸收率的特点，因此在包括准分子激光器的激光系统应用中广受欢迎。TECHSPEC® 氟化钙 (CaF2) 窗口片 非常适合在真空紫外（VUV）和中波红外（MWIR）、紫外光谱系统、低温冷却热成像系统中工作的气体探测器中作为保护窗口使用，还可在需要宽带基底传输时作为镀膜基底使用。
请注意: 氟化钙是一种相对较软的光学材料，比一般的玻璃窗口片更容易被划伤。
