摘要： This invention provides a photographing optical lens assembly comprising, in order from an object side to an image side: a first lens element with positive refractive power having a convex object-side surface; a second lens element with negative refractive power having a concave object-side surface and a concave image-side surface, the object-side and image-side surfaces thereof being aspheric; a third lens element having a concave image-side surface, the object-side and image-side surfaces thereof being aspheric, at least one inflection point formed on the image-side surface; wherein there are three lens elements with refractive power. Such an arrangement of lens elements can effectively reduce the total track length of the lens assembly, attenuate the sensitivity of the optical system and obtain higher resolution.

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.
