Abstract
Stop apparatuses and optical apparatuses are provided herein. One or more stop apparatuses configured to determine a light amount in each of a first optical system and a second optical system that are arranged in parallel may include a single drive source, a first aperture stop to be driven by the drive source to change the light amount in the first optical system, a second aperture stop to be driven by the drive source to change the light amount in the second optical system, and an adjusting mechanism configured to adjust a light amount passing through one of the first aperture stop and the second aperture stop independently of a light amount passing through the other one of the first aperture stop and the second aperture stop.

A stop apparatus configured to determine a light amount in each of a first optical system and a second optical system that are arranged in parallel, the stop apparatus comprising:
- a single drive source;
- a first aperture stop to be driven by the drive source to change the light amount in the first optical system;
- a second aperture stop to be driven by the drive source to change the light amount in the second optical system;
- and
- an adjusting mechanism configured to adjust a light amount passing through one of the first aperture stop and the second aperture stop independently of a light amount passing through the other one of the first aperture stop and the second aperture stop.
