Japanese Patent JP2023018454
Kind Code:
A
Abstract:
To provide an optical system that can form an optical condition according to a purpose, and a lens device, an imaging apparatus, and a projector having the optical system.SOLUTION: An imaging apparatus 100 includes an objective lens 1 and an optical element 2 located on the opposite side of the objective lens 1 to the side where an object is arranged. The optical element 2 includes: a rotatably supported rotary member 21; and a plurality of filters 22A to 22D formed in the rotary member 21, the filters being optically arranged in positions perpendicular to the optical axis 1J of the objective lens 1 and having different optical transmission characteristics. The rotary axis 21J of the rotary member 21 is not parallel to the optical axis 1J of the objective lens 1.SELECTED DRAWING: Figure 1
