摘要： To reduce or prevent adhesive particles from being scattered toward a light-emitting portion of an arc tube and an auxiliary reflecting surface of an auxiliary mirror even when an inorganic adhesive injected for fixing the auxiliary mirror to the arc tube is boiled, a method of manufacturing a light source lamp includes: setting a light-reflecting surface of the auxiliary mirror so as to face the light-emitting portion of the arc tube and injecting an adhesive into a gap between the auxiliary mirror and the arc tube; heating and curing the adhesive from a side nearer to the light-emitting portion of the arc tube; and attaching the reflector to the arc tube with the auxiliary mirror fixed thereto. For example, a heated air blowoff and light irradiation toward the adhesive form the side nearer to the light-emitting portion of the arc tube may be performed. Further, a projector includes: an illumination system with the light source lamp; an optical modulator; and a projector lens.

摘要： The present invention provides a technique for improving the optical characteristics of a light-selective prism. By cutting a block along a plane perpendicular to a first direction, a plurality of first small blocks are obtained. A first selective film is formed on the cut face of the first small block, and the plurality of first small blocks are stuck together so as to obtain a first processed block in which the first selective film is located at the interface of adjacent two first small blocks. Next, by cutting the first processed block along a plane perpendicular to a second direction that is substantially perpendicular to the first direction, a plurality of second small blocks are obtained. A second selective film is formed on the cut face of the second small block, and the plurality of second small blocks are stuck together to obtain a second processed block in which the second selective film is located at the interface of adjacent two second small blocks. Light-selective prisms in which two kinds of selective films are formed on an almost X shape interface is obtained from the second processed block.
