Abstract:
A projector apparatus, comprising:a light modulation optical system including a light separator which separates white light into a plurality of light components with respective wavelength bands, a light modulator which controls an intensity of each of said plurality of light components, and a light composer which composes the controlled plurality of light components, wherein the light separator and light composer are vertically stacked; a projection lens for projecting the controlled plurality of light components in the light modulation optical system; a light source optical system for outputting the white light, the light source optical system having an optical axis which is at least substantially parallel to, but displaced from, an optical axis of the light modulation optical system; and a focusing lens for focusing the white light output from the light source optical system, wherein said focusing lens has an optical axis coincident with the optical axis of the light separator so that light from the light source not coincident with the optical axis of the light separator is refracted to the optical axis of the light separator.
