Audited Supplier Optical Windows are flat, optically transparent plates that are typically designed to maximize transmission in a specified wavelength range, while minimizing reflection and absorption. They are often used to protect optical systems and electronic sensors from an outside environment. Because windows introduce no optical power into a system, windows should be selected based on the material transmission properties, optical surface specifications, and the mechanical properties that match your application.
We supply a range of optical windows in a selection of materials to meet all scientific instrument applications from UV-Visible and NIR wavelengths.
Visible Optical Windows are designed to prevent electronic sensors, detectors, other sensitive optical components from being saturated or damaged by light. Visible Windows are ideal for use in imaging applications or as protective displays for industrial or environmental applications. Visible Optical Windows do not introduce magnification power into a system. Visible Windows should be selected based on material transmission or mechanical properties.
