光学部材、レンズ装置及び撮像装置
Abstract:
複数の開口領域を備える光学部材、レンズ装置及び撮像装置を提供する。レンズ装置（１００）は、撮像光学系（１００Ａ）と、撮像光学系（１００Ａ）を透過する少なくとも一部の光線を偏光させる第１偏光部（１０１）と、第１偏光部（１０１）よりも像側に配置され、撮像光学系の瞳位置又は瞳位置の近傍に配置されるフィルタユニット（１３０）であって、撮像光学系（１００Ａ）の光線を透過させる、第１開口領域及び第２開口領域を含む複数の開口領域と、第１開口領域及び第２開口領域に配置され、少なくとも一部の波長帯域がそれぞれ異なる光を透過させる複数の波長選択フィルタと、第１開口領域及び第２開口領域に配置され、偏光方向が互いに異なる複数の偏光フィルタを有する第２偏光フィルタと、を含むフィルタユニット（１３０）と、を備える。
Abstract(English):

Provided are: an optical member comprising a plurality of aperture regions; a lens device; and an imaging device. A lens device (100) comprises: an imaging optical system (100A); a first polarization unit (101) which polarizes at least some light rays transmitted through the imaging optical system (100A); and a filter unit (130) which is disposed more on the image side than the first polarization unit (101) and disposed at a pupil position of the imaging optical system or in the vicinity of the pupil position, the filter unit (130) including a plurality of aperture regions including a first aperture region and a second region which transmit the light rays of the imaging optical system (100A), a plurality of wavelength selection filters which are disposed in the first aperture region and the second aperture region and transmit light, at least some of which has different wavelength bands, and a second polarization filter which is disposed in the first aperture region and the second aperture region and has a plurality of polarization filters with mutually different polarization directions.
