摘要： An optical device is provided which includes a plurality of optical modulation devices, plurality of optical elements, and a prism having a plurality of luminous flux incidence surfaces positioned on a luminous flux irradiation-side of each optical element. The optical device includes a holding member which holds at least one of the plurality of optical modulation devices and a pair of light-transmissive substrates. In one implementation, an irradiation-side substrate disposed on the luminous flux irradiation-side of the optical element has a dimension larger than that of the optical element, and the irradiation-side substrate is secured to the luminous flux incidence surface of the prism, an aperture is formed in the holding member, and the holding member is attached to the irradiation-side substrate so as to cover the optical element. Detailed information is provided in the Description of Exemplary Embodiments below, and the inventions are defined by the appended claims.

摘要： A light source device (40) attached to an optical equipment provided with a light-source cooling fan (3) has a light source (401), a reflector (402), a light-transmissive component (51) that closes the light-irradiation side of the reflector (402) and a light source housing (50) that houses the above components. An opening (402A) for introducing a cooling air is formed on the reflector (402) and an opening (52) is formed on the light source housing (50) at a position corresponding to the light source housing (50). A duct (53) of which light-irradiation side is opened is provided on the opening (52). When the light source device (40) is attached to the optical equipment, the duct (53) protrudes toward the light-irradiation side to be connected with the fan (3). The opening (52) is opened in accordance therewith, so that the air from the fan (3) is introduced into the reflector (402).
