Total Internal Reflection Prism(TIR prism) is a combination of two laminated prisms, a TIR prism effectively directing the incident light to DMD chip, the expected image is projected following the light beam reflected by DMD chip.TIR /RTIR prism are applied in DLP projection system, light path is changed by using TIR to save the space in optical engine and enhance contrast level of the system.
In an RTIR architecture, a reverse total internal reflection (RTIR) prism is used in a projection path between a spatial light modulator and the projection optics.
SICUBE offers ODM and OEM of high end optical components,like TIR prism and RTIR prism.
