Document Type and Number:
WIPO Patent Application WO/2019/167876
Kind Code:
A1
Abstract:
The present invention addresses the problem of providing an optical filter that is capable of suppressing the color shading and the ghosting in a camera image while exhibiting high light transmittance characteristics in the visible light wavelength region, and has a suitable heat resistance so that the optical characteristics thereof can be maintained even after long term exposure to a high temperature. The optical filter according to the present invention is characterized by having a base material that satisfies a requirement (a), and having a dielectric multi-layer formed on at least one side of the base material. (a): The base material includes a layer containing an organic pigment (S) that has an absorption maximum in a wavelength range between 900 nm and 1200 nm, inclusive.
