LIGHT SOURCE APPARATUS

摘要

A light source apparatus includes first and second light sources having different maximum light amounts used, a first light amount detection section detecting a light amount of first light of the first light source, a second light amount detection section detecting a light amount of second light of the second light source, a light amount limiting section limiting a light amount of light incident upon the second light amount detection section so that light amounts detected in the first light amount detection section and the second light amount detection section match a predetermined value within a detection range when light with the maximum light amounts used are emitted from the first light source and the second light source, and a control section controlling amounts of light emission of the first light source and the second light source based on detection results of the first and second light amount detection sections.

1. A light source apparatus comprising:
a first light source that emits first light with a first light amount as a maximum light amount used; a second light source that emits second light with a second light amount higher than the first light amount as a maximum light amount used; a first light amount detection section provided on an optical path of the first light and configured to detect a light amount of the incident first light; a second light amount detection section having a detection range identical to a detection range of the first light amount detection section, provided on an optical path of the second light, and configured to detect a light amount of the incident second light; a light amount limiting section that limits a light amount of light incident upon the second light amount detection section so that the light amounts detected in the first light amount detection section and the second light amount detection section match a predetermined value within the detection range when light with the first light amount and light with the second light amount are emitted from the first light source and the second light source; and a control section that controls amounts of light emission of the first light source and the second light source based on detection results of the first and second light amount detection sections.
