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 prism 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 good surface finish, flatness as high as l/10 and high accuracy are available in Photonchina.
With the rich experience in producing these prisms and high precision equipment both in making and inspection, Photonchina has been satisfying customers worldwide for more than decades. You may choose below from different level of products precision from standard level to Photonchina’s ability,which indicate higher requirements such as angle tolerance, surface quality etc. to meet the demand in various applications.
Materials: N-BK7, UV Fused Silica, CaF2, ZnSe, or Ge。Uncoated or AR coating requirements upon customer’s request.
