Infrared Material Lens

Infrared germanium lenses are ideal for thermal and infrared imaging applications because of their ultra-high refractive index and their ability to work in harsh environments. 

ZnSe lens has the characteristics of low absorption and excellent thermal shock resistance. ZnSe lens has been widely used in the field of infrared component window lens and spectral analysis ATR prism. ZnSe is also a good choice for CO2 laser components.

ZnS lens material has high purity and high refractive index uniformity. It has excellent  hardness, which makes it often used in harsh environments where high intensity infrared transmission is required.

Sapphire is the hardest oxide crystal material, and its high damage threshold makes it stable in harsh environments. It can be used in infrared laser systems and spectral analyzers.
