  • Extremely small loss for p-polarized beam
  • Separated by wavelength light is conveniently turned by 90° angle with minimum deviation
  • UVFS prisms provide 1.26° separation between 532 and 1064 nm

In a Pellin-Broca prism, an ordinary dispersing prism is split in half along the bisector of the apex angle. Using a right angle prism, the two halves are joined to create a dispersing prism with an internal right angle bend obtained by total internal reflection. The entrance beam is deviated at 90° angle to its initial direction.
