Title:
撮像レンズ及び撮像装置
Document Type and Number:
Japanese Patent JP7443309
Kind Code:
B2
Abstract:
An imaging lens capable of increasing, compared to an imaging lens having a wide light transmission region, light transmittance in a specific wavelength region within a near-infrared wavelength region, and an imaging apparatus using the imaging lens are provided. An imaging lens includes a plurality of lenses, in which in a near-infrared light wavelength region, by providing a coating on at least a part of the plurality of lenses, light transmittance on a short wavelength side of a near-infrared light peak wavelength region NIR including 1550 nm is reduced from light transmittance at a short wavelength end of the near-infrared light peak wavelength region NIR as a wavelength is decreased, and light transmittance on a long wavelength side of the near-infrared light peak wavelength region NIR is reduced from light transmittance at a long wavelength end of the near-infrared light peak wavelength region NIR as the wavelength is increased.
