<p><P>PROBLEM TO BE SOLVED: To provide a method of manufacturing a reflector having increased reflection efficiency, a light source apparatus equipped with the reflector manufactured by the manufacturing method and a projector equipped with the light source apparatus. <P>SOLUTION: The reflector is manufactured by a raw pipe accommodation step, a heating step, a gas charging step, a degassing step and a cutting step. In the raw pipe accommodation step (A), a quartz glass tube 6 is accommodated in a molding die 5 having an inner surface formed to a shape corresponding to a reflection part 61 of the reflector reflecting incident light in one direction. In the heating step (B), a part of the quartz glass tube 6 accommodated in the molding die 5 is heated to an easily deformable state. In the gas charging step (C), high pressure Ar gas is encapsulated from one end E1 of the quartz glass tube 6 to form a reflection part 61 in the quartz glass tube 6. In the degassing step (D), degassing is performed from a gap V1 by pressure of the Ar gas encapsulated in the gas charging step. In the cutting step (E), the quartz glass tube 6 is cut to two at B1 and is further cut at both end parts B2, B2. <P>COPYRIGHT: (C)2008,JPO&INPIT</p> |
