发明名称 Projector and optical device
摘要 A projector includes a light source, a beam splitter for splitting a light irradiated from the light source into a plurality of partial light beams, a polarization converter for converting the light beam irradiated from the beam splitter into a predetermined linear polarization light beam, and a lens array for transmitting the plurality of partial light beams irradiated from the polarization converter to a light modulator, where the polarization converter and the lens array are integrated by a holding frame and are fixed to a fixing portion of a support, so that the polarization converter and the lens array can be attached to the fixing portion of the support while adjusting position of the integrated component relative to the fixing portion, thus reducing trouble for position adjustment.
