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.
Round, rectangular, elliptical, flat, wedged or any other shape including cut-outs and drill holes- windows can be manufactured in almost any shape. Holes may also be drilled at an angle to the surface normal.
Anti-reflection (AR) coatings are generally applied to both surfaces of a window to prevent back reflections, interference effects, ghost images and light loss.
