Document Type and Number:
Japanese Patent JP2016114632
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a light intensity adjustment device that can adjust the intensity of light while preventing a reduction in image quality, and an imaging device.SOLUTION: There is provided a light intensity adjustment device comprising a light intensity adjustment filter advancing and retreating in a light passing path, where the light intensity adjustment filter includes a flange part that continuously changes so that the thickness of the entire filter is gradually reduced from a filter tip part on an approaching direction toward an end on the opposite side in an advancing and retreating direction with respect to the light passing path, the flange part reduces a phase difference between transmitted light at the filter tip part of the flange part and passing light passing through the light passing path before approaching the filter tip part.SELECTED DRAWING: Figure 2
