OPTICAL TRANSMISSION UNIT AND IMAGE CAPTURING APPARATUS
First Claim
1. An optical transmission unit comprising:
- a plurality of optical transmission paths;
a first aperture limiter configured to limit an aperture on an entrance end of each of the plurality of optical transmission paths;
a second aperture limiter configured to limit an aperture on an exit end of each of the plurality of optical transmission paths; and
a moving unit configured to rotationally move, around an optical axis direction of the transmission paths, at least one of the plurality of optical transmission paths, the first aperture limiter, and the second aperture limiter so that a moving direction and a moving amount of the aperture limited by the first aperture limiter can be equal to those of the aperture limited by the second aperture limiter.
