Right angle prisms (RAP) are widely used for rotating images 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 for 45 degrees mirrors. Please refer to our right angle prism mirrors for the details.
