Title:

STEREO LENS DEVICE AND IMAGING APPARATUS

Document Type and Number:

Japanese Patent JP2023050330

Kind Code:

A

Abstract:

To arrange holding mechanisms that hold image-side lens groups in the interval between the image-side lens groups while reducing the interval in a stereo lens device.SOLUTION: Two optical systems 201R, 201L arranged in parallel in a stereo lens device 200 have, in order from an object side to an image side, first lens groups 211R, 211L, second lens groups 221R, 221L, and third lens groups 231R, 231L. An optical path is bent between the first lens groups and the second lens groups and between the second lens groups and the third lens groups, and thereby an optical axis interval L2 between the two third lens groups is narrower than an optical axis interval L1 between the two first lens groups. Parts 238, 233e of one holding mechanism of two holding mechanisms that hold the two third lens groups are arranged inside a recess 233f provided in the other holding mechanism, and parts of the other holding mechanism are arranged inside a recess provided in the one holding mechanism.SELECTED DRAWING: Figure 27
