Optical Windows

Windows are applied to isolate different physical environments while allowing light to pass. When selecting windows you should consider materials, transmission, scattering, wavefront distortion, parallelism and resistance to certain environment. Tempotec offers a wide range of different materials and different degree of precision windows. Tempotec provides serveral kinds windows for defferent applications. Customer designed special windows are available.

Ellipitical Window / Brewster window
The window cutted as brewster angle, It's used as polarizer in laser cavity. Brewster Windows are uncoated substrates which are used as polorizers, typically within a laser cavity. Positioned at Brewster's Angle the P-Polarization portion of the light will pass through the window with _disibledeven...
