Product Description

Sapphire Window, Hard Windows, 150nm-4.5μM Windows

Overview:

Sapphire Windows provide a transmission range extending from the UV to the MIR. The uncoated sapphire windows are designed for applications in the 150 nm - 4.5 μm range. AR coated sapphire windows feature anti-reflective coatings for 1.65 µm - 3.0 µm or 2.0 µm - 5.0 µm on both sides.

 

Sapphire windows are well known for its exceptional surface hardness. They can only be scratched by a few materials other than themselves.

 

Our sapphire windows are z-cut so that the c-axis of the crystal is parallel with the optical axis, removing birefringence effects on transmitted light.
