Triangular optical prism P-FS series

dispersionanamorphicprecision

Prisms are mainly used to reflect the beam in some specific direction and to have the required orientation of the image. The most common type of prism is the right angle. When the beam enters from the hypotenuse side it’s reflected back by total internal reflection with a minimum beam deviation. Hypotenuse face is typically coated with AR to have minimum reflection loss. • Material : UVFS, BK7, CaF2 • Dimensions tolerance : +/- 0.2 mm • Surface quality : 40-20 S-D • Surface flatness : λ/4 at 633 nm • Angular tolerance : +/- 3 arcmin *standard specifications
