产品说明

锗(Ge)是一种常用的红外光学晶体材料,典型透光范围约为2–16 μm,具有高折射率、较高硬度及良好的化学稳定性等特点,尤其适用于8–12 μm长波红外波段,广泛应用于红外热成像、红外检测、光谱分析及相关光学系统。

锗在可见光波段基本不透光,可用于制作红外长波通滤光元件,也常用于加工红外透镜、窗口片及其他精密光学器件。由于锗的折射率较高,通常建议采用增透镀膜,以降低表面反射损耗并提高透射效率。

温度特性: 锗的红外吸收对温度较为敏感,随着温度升高,其红外透过性能可能明显下降,尤其在较短的红外波长区域。因此,不建议在高温环境下直接使用未经验证的锗透射光学元件,具体适用温度应结合工作波长、材料厚度及实际透过率确定。

使用及储存注意事项: 锗晶体属于硬脆材料,使用时应避免碰撞、跌落及不当擦拭。正常操作完整光学元件时建议佩戴洁净手套,避免表面污染;加工、研磨时应避免吸入粉尘。产品应存放于清洁、干燥的环境中。

镀膜及定制服务: 图知光学可根据客户需求提供不同尺寸、精度及增透镀膜的锗(Ge)红外窗口片、透镜及其他定制光学元件。
