Abstract

A lens device includes an imaging optical system and an optical member. The optical member is disposed near a pupil of the imaging optical system in a state where an optical axis of the optical member coincides with an optical axis of the imaging optical system. The optical member includes a frame that includes a plurality of aperture regions, a plurality of optical filters that are disposed in at least one of the plurality of aperture regions and include two or more optical filters transmitting light having at least some wavelength ranges different from each other, and a plurality of polarizing filters that are disposed in at least one of the plurality of aperture regions and have different polarization directions. The lens barrel has a slit, and the optical member is insertable into and removable from the imaging optical system through the slit.
