Abstract
An optical lens assembly for generating light beams from near infrared light beams emitted by a structured light generating unit having light sources and passed through the optical lens assembly is provided. The optical lens assembly includes a first lens element, a second lens element and a third lens element arranged along an optical axis in a sequence from a light output side to a light input side. The optical lens assembly satisfies: SL/AAG≤6.500, wherein SL is a distance from an optical surface of one of an optical elements closest to the light output side of the optical lens assembly to the structured light generating unit having the plurality of light sources along the optical axis, and AAG is a sum of the air gaps among all lenses having refracting power of the optical lens assembly along the optical axis.
