Right Angle Prisms
Right angle prisms (RAP) are widely used for rotating image and redirecting the input light. They serve as a mirror to deviate light through 90 degrees and also as a retro-reflector to deflect light through 180 degrees by total internal reflection. 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.
Photonchina Laser Grade Right-Angle Prisms are fabricated by special selection optical materials with low scatter and absorption. Standard size laser grade right angle prisms, with better surface finish, flatness as high as l/10 and high accuracy are available in Photonchina.
