Right angle prisms are some o f the versa t i le prisms available. The three pol ished surfaces of a prism which are coated or knife edged reflect beams internally and externally. Then i t re f l ec ts i npu t beams in 90o or 180o just
as a total reflection mirror or a retro-reflector or divides beams into two directions. Right angle prisms are easier to mount, more stable and stronger against mechani-cal stress than mirrors because they have wider areas to be contact and have typi-cal angle, 45o and 90o.
