China Right Angle Prisms Optical Prisms

Right Angle prisms are used to direct a beam of light at 90 degrees from the incident. They may also be used to retroreflect a beam.

For collimated beams, the index of refraction for BK7 is sufficient to guarantee TIR (total internal reflection) at the hypotenuse for wavelengths in the visible and near infrared regions as long as the light is normally incident to the entrance aperture, and the hypotenuse is kept clean.

A prism with an aluminized hypotenuse is recommended for applications where the prism is frequently handled, or where convergent or divergent beams are used.

A wide variety of antireflection coatings may be used on the entry faces of the Right Angle prism to reduce reflection loss.
