Optical Survey prisms are a specially designed retro reflector, specifically a corner reflector, that is used to reflect the Electronic Distance Measurement (EDM) beam of a total station.

Prisms reduce the scatter of the beam as it is reflected back to the total which allows for both a more accurate measurement and a longer range that the measurement can be made.
