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 (UV-grade, optical grade or IR-grade) and sapphire optical windows.

An optical glass window is a piece of glass that has been specially manufactured for use in optical applications. Optical glass is made from a specific type of silica sand, which is heated and cooled very slowly to create a very pure, homogeneous glass.
This type of glass has very low levels of impurities, which makes it ideal for use in optical applications where light needs to be transmitted with minimal distortion. Optical glass is also very resistant to thermal shock, meaning it can withstand sudden changes in temperature without shattering. Glass windows are used in a wide range of optical devices, including telescopes, cameras, and binoculars. They are also used in some types of medical equipment, such as x-ray machines.
