Optics: Window & Diffuser

Optical windows are flat, parallel plane plates that are frequently used to protect electronic sensors and detectors from the surrounding environment. Optical windows should be selected based on the substrate's transmission characteristics and mechanical properties. Optical windows do not affect the magnification of the system. Edmund Optics offers optical windows made from various substrate materials such as germanium (Ge), silicon (Si), N-BK7, UV-grade synthetic quartz, zinc selenide (ZnSe), and potassium bromide (KBr). We also provide multiple anti-reflective coating options for ultraviolet (UV), visible, and infrared (IR) applications.
