       Windows are plane-parallel planes that are often used as protective windows for electronic sensors or detectors from outside environments. Windows do not change the amplification factor of the system. The substrate materials include various optical glasses, K9, ultraviolet fused silica, infrared fused silica, as well as crystal materials such as calcium fluoride (CaF2), magnesium fluoride (MgF2), zinc selenide (ZnSe), germanium (Ge), silicon (Si), and provide various optical coatings such as AR coating, high-reflection coating, spectroscopic coating, and metal coating. Broadband AR coating can be used in ultraviolet, visible, near-infrared, and mid-infrared bands. OMTOOLS offers windows made of different materials to meet various commercial and scientific applications.
