Filter and imaging apparatus |
| abstract |
Provided a filter and an imaging apparatus for obtaining a higher-quality multispectral image in which the tint of the image is uniform. The filter includes: an optical filter layer; and a patterned retardation layer that is laminated on the optical filter layer. The optical filter layer includes at least three reflective layers that are formed of a cholesteric liquid crystal layer, and the reflective layers have different reflection center wavelengths. Alternatively, the optical filter layer includes a reflective layer that is formed of a cholesteric liquid crystal layer having at least two different reflection center wavelengths. The patterned retardation layer has a slow axis in a direction corresponding to the reflection center wavelength of the reflective layer. |
