  Right angle prisms (RAP) are widely used for rotating image and redirecting the input light. They are the main components for polarizing and non-polarizing cube beamsplitters.
  The total internal reflection (TIR) in the right angle prisms with specific anti-reflection (AR) coatings on the two leg sides make themselves the perfect alternatives of 45 degree mirrors. Please refer to our right angle prism mirror for the details.

NOTE:

  1. Some other sizes may be available. Please contact us for other custom size RAP.
  2. Spectral Optics provides various coating services. Please contact us and check up the availability for any coating if needed.
