Optical Window
    Optical window is applied to isolate different physical environments while allowing light to pass. When selecting optical window you should consider material, transmission, scattering, wavefront distortion, parallelism and resistance to certain environment. Simphoton offers a wide range of different materials and different degree of precision windows.

Simphoton provides serveral kinds windows for defferent applications. Customer designed optical window are available upon request.

Material: BK7, Fused silica, Sapphire, Quartz, Silicon, MgF2, CaF2, ZnSe, etc.

Round or rectangle shape

Ideal for interferometer flat, laser window, beamsplitter substrate, or parallel plate.
Commercial window commonly used as sight glass, instrument window, beamsplitter substrate, vacuum window, etc.

Wedge window (Wedge prism) is a wedge shaped piece of glass which refracts light rays, thus establishing a critical angle.
Brewster window is cutted as brewster angle, It's used as polarizer in laser cavity.
Round or rectangle shape as above With perfect surface polishing, laser window is fit for high power laser applications.
Round or rectangle shape as above Magnesium Fluoride (MgF2) has excellent transmission in the UV wavelength. MgF2 window can be used for excimer & Nd:YAG laser.
Round, rectangle shape
Custom shape availabe
Sapphire is one of the hardest optical material. It has wide transmission range from 180nm - 4500nm. It's an ideal material for optical window.

AR coating is available by request.
R<0.25%@single wavelength
Ravg<0.5%@broadband wavelength range
