Corner cube prism (retro-reflectors) OQCCB-20 is inner total reflected prism on the base of the priciple of critical angle, it is not influented by the angle of incident and it can make the incident light reflecting to 180 degre, that is to say,any incident light that comes into the aperture will be reflected back totally.
