Optical Windows are flat plane-parallel plates, which are often used to protect electronic sensors or detectors without blocking optical transmission. Optical Windows do not change the magnification of a system. Ronder offers a variety of optical windows, which cover the wavelength range from ultraviolet (UV) to infrared (IR).

 

 

Ronder offers high precision windows either in multitudious substrates ( Fused Silica, CaF2, Si, BK7) or coated parts with multiple anti-reflection coating options covering wavelength range of Ultraviolet (UV), visible, or Infrared (IR).  Millions of stock and custom precision windows are manufactured by different processing methods such as double-sided polishing, conventional polishing and ion beam figure(IBF) to guaranty high surface figure, low scatter, and high laser damage threshold to satisfy even the most demanding requirements.

Brewster window are manufactured based on the total reflection character of the material, the S polarizing light is reflected partially and the P polarizing light almost transmitted fully when the light passes through at the fixed angle of incidence (Brewster Angle of the material)

Reduce Loss of P-Polarized Light

Circular Profile When Oriented at 55.57°

Great for Use in Laser Cavities.
