Optical windows are transparent glass components that are used to transmit light of a designed wavelength range while simultaneously minimizing reflection and absorption.
They are used as a protective element between two environments and their impact on the passage of light is neutral.
Standard Materials:
N-BK7, fused silica windows, IR windows & UV windows (UV-grade, optical grade or IR-grade) and sapphire optical windows.
Also possible: CaF2, BaF2, MgF2, Ge, Si, ZnSe, etc.
Custom Optical Window Designs including cut-outs & drill holes
In almost any shape
