Optical filter and equipment using optical filter |
| abstract |
PROBLEM TO BE SOLVED: To provide an optical filter capable of achieving both color shading suppression and ghost suppression of a camera image at a high level, which cannot be sufficiently achieved by a conventional optical filter. The optical filter of the present invention has a substrate that meets the requirements (a), (b), (c) and (g) and meets specific requirements: (a) wavelength 650 nm or more and 760 nm. It has a layer containing the compound (A) having an absorption maximum in the following region; (b) The shortest wavelength (X 1 ) having a transmittance of more than 10% to 10% or less in the region of wavelength 650 nm or more, and a wavelength of 650 nm. In the above region, the absolute value | X 1 −X 2 | of the difference from the shortest wavelength (X 2 ) at which the transmittance is less than 10% to 10% or more is 50 nm or more; (c) wavelengths 900 nm, 1000 nm and All have a transmittance of 65% or less at 1100 nm; (g) contains a compound (S) having an absorption maximum in a region having a wavelength of 1050 nm or more and 1200 nm or less.
