High Quality Corner Cube Retroflector 

Prisms are solid glass optics that have been ground and polished to form geometrically and optically distinct shapes. The angle, position, and number of optical flat crystals help define type and function. A notable feature of prisms is their ability to mimic the reflection of light in the prism medium as a planar mirror system. Replacing reflector components may be a useful prism application as they both refract or fold light rays and alter image alignment. To achieve an effect similar to a single prism, it is usually necessary to use multiple reflectors. Therefore, replacing several mirrors with a prism can reduce potential calibration errors, improve accuracy, and reduce the size and complexity of the system.
