摘要： A light source unit including an arc tube having a light emitting section, sealed sections, an elliptic reflector, and a secondary reflecting mirror to cover the front side of the light emitting sections and reflect a luminous flux radiated from the light emitting section toward the elliptic reflector. The center of discharging emission from the arc tube is disposed at a first focal position of the elliptic reflector, and the secondary reflecting mirror is configured as a separate member from the arc tube, so that the outer peripheral portion of the secondary reflecting mirror is accommodated within a circular cone connecting a second focal position of the elliptic reflector and the distal end of the front sealed section of the arc tube when being mounted to the front sealed section of the arc tube.

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.
