Isosceles Prisms

Materials: UV grade fused silica (UVFS), CaF2 crystal,
  N-SF10, N-SF11, N-BK7, N-LAK21 or N-LAF35 glass.
Becomes Brewster prisms at the proper apex angle with
  an extremely small loss for p-polarized beam.
Widely used for GVD correction in femtosecond lasers.

     Geometry

Note: The apex angles indicated are the ideal angles for Brewster incidence at the specified wavelengths. The insertion loss is very insensitive to the apex angle: +/-0.2 deg deviation from the ideal apex angle would not affect the performance.
