Plane parallel windows are widely used as transfer optics and shields. Optical windows are used to separeate two different enwironments while still allowing light to pass through.Optics windows can be applied on projection system, imaging system, Optical measurement system. And its materials cover from BK7 etc optical glass to IR CaF2, MgF2, Ge, ZnSe, Mono Si, ZnS, quartz, Sapphire, etc crystal materials.
