Optical Windows are flat, plane-parallel plates that are often used as protective barriers for electronic sensors or detectors from outside environments. Optical Windows are offered in a variety of substrates, such as Germanium (Ge), Silicon (Si), N-BK7, UV Fused Silica, Zinc Selenide (ZnSe), or Potassium Bromide (KBr). Multiple anti-reflection coating options are available for the Ultraviolet (UV), visible, or Infrared (IR).

Interferometry Windows are used to measure the flatness of optical surfaces or certain optical components to ensure accuracy for a wide range of quality assurance or inspection applications. Interferometry Windows are optical surfaces that have been polished to an extremely precise level of flatness which are used as reference plates.

Infrared (IR) Windows are molded in an extremely thin and flexible 0.457mm thickness, milky white plastic. The thin design consistent across the window surface, large apertures, and minimal thermal expansion coupled with low absorption from 8 – 14μm make them ideal for a range of infrared applications.

UV Windows are Optical Windows designed for optimal performance in the Ultraviolet (UV) spectrums. UV Windows are used in many laser applications.

Visible Windows are Optical Windows designed for use in the visible spectrum. Visible Optical Windows are designed to prevent electronic sensors, detectors, other sensitive optical components from being saturated or damaged by light.
