Abstract

A prism module has a first prism, a second prism having a first surface next to a first surface of the first prism, a first beam splitting device formed between the first surface of the first prism and the first surface of the second prism for allowing part of ultra violet (UV) light, visible light in a first and a second colors to pass, and for reflecting part of the UV light and visible light in a third color, a third prism having a first surface next to a second surface of the first prism, and a second beam splitting device formed between the first surface of the third prism and the second surface of the first prism for allowing part of the UV light and the light in the second color to pass, and for reflecting part of the UV light and the light in the first color.
