Pellin Broca Prism(BA7A or Fused Silica) 

·Low loss for p-polarized beam ·Versions available for femtosecond GVD correction ·Saparation of harmonic wavelengths ·High power use Pellin Broca prisms are constant deviation  (90°)  dispersing prisms， the input angle is arranged so that total internal reflection occurs at the internal face. This will provide a constant 90° deflection for the beam with dispersion. If the input beam enters the long side of the prism the longer wavelengths will be deviated less. These prisms provide a convenient way to compensate for group velocity dispersion in ultra-fast lasers or to separate harmonic wavelengths in an incoming laser beam.
