Isosceles Brewster Prisms (IBP) 

Low loss for p-polarized beam
Selection of wavelength from multi-spectral laser
Tuning by changing angle of incidence
Version available for femto-second GVD correction

Brewster Prisms are isosceles prisms arranged to have an apex angle which permits a ray entering at the Brewster angle to pass at minimum deviation. They are ideal for selection of wavelengths or tuning of laser output. If required for use with femto-second lasers please contact us and ask for the ultra-fast version.
