Prismes


Corner cubes have the property that light incident on the prism face is deflected 180 degrees regardless of its angle of incidence.
The hollow retroreflector is similar to the corner cube; it reflects the incident light back to its original source.
Rectangular prisms that are not coated can be used in various applications, such as total internal reflection of critical angles and wavelength dispersion.
