Windows & Substrates

Optical windows are transparent substrates with highly parallel polished surfaces, used for beam transmission, system isolation, or surface referencing.

Standard shapes include circular, square, and rectangular, with options for flatness, wedge, and coating.

They serve as protective elements or optical bases for mirrors, beamsplitters, and filters in precision systems.
