摘要： This invention provides an NIR imaging lens assembly comprising a lens element with refractive power made of a visible-light-absorbable material, and a filter or a filter film formed on one lens element with refractive power for filtering out infrared light, wherein the number of lens elements with refractive power in the NIR imaging lens assembly is N, and wherein N≧2. The above lens arrangement allows light in a specific NIR wavelength range to pass through the lens assembly, thereby reducing interferences or influences from light in the other wavelength ranges. As a result, the resolution of the imaging lens assembly is improved, and its total track length is reduced effectively so that the entire lens system can be compact.
