Window
The caf2 Window is made from Calcium Fluoride material, which has transparent range from 170-7800nm. The refractive index is 1.399 at 5000nm. It has little hygroscopic susceptibility and high thermal expansion coefficient. CaF2 Windows are relatively soft
The Window is made from Fused Silcia material, which has transparent range from 185-2500nm. The refractive index is 1.4858 at 308nm. It has low thermal expansion coefficient. The Fused Sildica window has better performance from UV to IR spectrum. Also, it
The Window is made from sapphire material, which has transparent range from 180-4500nm. The refractive index is 1.755 at 1000nm. It has strong hardness. The Sapphire window is suit for scratch resistance application with better transmission over the wide
The Window is made from BK7 material, which has transparent range from 330-2100nm. The refractive index is 1.5164 at 588nm. The BK7 window has good performance over visible and near IR spectrum for most application.
