Product Description

 refer to a piece of transparent optical material that allows light into an optical instrument. They are pieces of optical glasses with ground and polished faces that are relatively parallel. Optical windows are applied for protecting fragile optical components inside an equipment, they are adopted to isolate two physical environments while allowing light to pass.

K9/Bk7/ B270/ Sapphire windows are ideally suited for industrial applications. Available uncoated or with a MgF2 anti-reflection coating, windows are often used as a protective element between two environments.
