  • Optical lens assembly and imaging lens with infrared ray filtering
    Patent number: 9851531
    Abstract: Example embodiments provide for an optical lens assembly and imaging lens with IR light filtering. The lens comprises a body having two surfaces and a plurality of layers of optical thin film layered along a direction formed on at least one surface. The optical thin films comprise less than 20 layers and thicker than 400 nm and thinner than 2000 nm thickness. Through the alternately layered layers of optical thin film, the transmittance of the lens for incident light in infrared ray band is reduced. Therefore, the infrared ray is mostly filtered without use of an additional infrared ray filter.
