  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.
