ABSTRACT:
To provide an optical apparatus, and a projector which can avoid the mutual positional deviations of a plurality of optical modulation devices and can form a good optical image free from pixel deviations. An optical apparatus includes three optical modulation devices which modulate respective color lights in accordance with image information, a cross dichroic prism which synthesizes the color lights modulated by the respective optical modulation devices, and pin spacers. Each of the optical modulation devices is fixed to the cross dichroic prism through the pin spacers. Each of the pin spacers is constructed of two pin-like protrusions, and a coupler which couples the two pin-like protrusions to each other at the parts of these pin-like protrusions as are remote from the end parts thereof on the side of the cross dichroic prism.
