Dichroic Prism

A dichroic prism divides light into red, green, and blue, to form three pictures that utilize these corresponding colours from the LCD (HTPS) panels. Colour and image are recomposed by reflecting red and blue light and transmitting green light. The prism is formed by combining four triangular poles to create one rectangular solid. High precision is required in the processing and adhesion of poles to avoid dark lines and double images caused by misaligned dichroic surfaces.
