• Windows are optical glass with ground and polished faces that are relatively parallel.Windows can be roughly divided into Optical Infrared Window, circular optical window, optical plane window, Optical Square Window and apartment window of Caf2.They are used to isolate two physical environments while allowing light to pass.Windows made of BK7 material have high transmission in the visible spectral region, do not scratch easily, do not degrade under normal operating environment and hence do not need any special precaution or treatment. Anti-Reflective Coating will provide higher transmission.
• When selecting windows, you should consider the following: material,transmission,scattering,wave front distortion,parallelism and resistance to certain environment. 
• China Star Optics offers all types of windows made from different materials. Such as N-BK7, Fused silica, sapphire,CaF2, Silicon, Borofloat, high borosilicate glass and other optical glass supplied by Schott and Chinese CDGM are available upon request. 
• Windows at shape of  round,quadrate, triangular or other polygonal are also available upon request.
• In addition, we provide a variety of  single layer or multiplayer anti-reflecting coating,HR,PR coatings on Optical Windows.
• UV Fused silica windows:These optical windows are precision manufactured using UV grade synthetic fused silica.In addition to superior transmission characteristics, synthetic fused silica exhibits higher thermal properties,exceptional purity and excellent environmental durability for demanding applications. 
• Windows are desiged for use in optical systems to separate two enviroments while passing a particular spectral range between them.Applications include laser set-ups(e.g.at Brewster's angle),emitter/detector protection devices, such as in sepctrophotometers and imaging systems using ultraviolet wavelengths.
• Specification of our optical windows as follow:
• Material:high borosilicate glass, BK7,UV-grade fused silica (JGS1) or other optical crystals materials
