Optical filters and their applications |
| abstract |
The present invention provides a thin optical filter having excellent near-infrared shielding properties and low reflection characteristics, and an apparatus using the optical filter, by improving the drawbacks of conventional optical filters such as a near-infrared cut filter. about. An optical filter comprising a base material satisfying the requirement (a) and an antireflection layer formed on at least one surface of the base material, and satisfying specific optical characteristics: (A) It has a layer containing the compound (A) having an absorption maximum in a wavelength region of 650 nm or more and less than 950 nm. [Selection figure] None |
