Corner Cube Prisms – Retroreflectors for Precision Ranging
Detailed Description:
Corner Cube Prisms (Retroreflectors) are three mutually perpendicular reflective surfaces that reflect incident light back along its original path, regardless of the angle of incidence. This retroreflection property makes them ideal for laser rangefinders, interferometers, and satellite tracking systems where stable light return is critical.
