<P>PROBLEM TO BE SOLVED: To provide a light source inspection apparatus capable of easily and accurately performing photometry the optical performance of a light source using an integration sphere. <P>SOLUTION: A light source inspection apparatus comprises: an integration sphere including a mounting section in which a light source of an inspection target can be mounted, and an emission port for emitting light beams toward the outside; photometric means which performs photometry, from the emission port, on reflection light beams in an area to perform photometry thereon of a fixed range on an inner circumferential surface of the integration sphere opposed to the emission port; and a baffle disposed between the area to perform photometry thereon and the mounting section. Emission light beams from the light source is prevented by the baffle from being incident directly to the area to perform photometry thereon and the photometric means is capable of performing photometry on the area to perform photometry thereon, thereby reducing differences in photometric results in accordance with the state of mounting the light source in the mounting section. Thus, photometry can be performed easily and accurately on the optical performance of the light source. <P>COPYRIGHT: (C)2013,JPO&INPIT |
