Abstract
An optical lens assembly is provided, including a first lens element, a second lens element, a third lens element, a fourth lens element, a fifth lens element, and a sixth lens element sequentially along an optical axis from a first side to a second side. The optical lens assembly satisfies a conditional expression of EFL/BFL≥3.800.

An optical lens assembly, comprising a first lens element, a second lens element, a third lens element, a fourth lens element, a fifth lens element, and a sixth lens element sequentially along an optical axis from a first side to a second side, wherein the first side is a light exit side or an object side, the second side is a light incident side or an image side, and each of the first lens element to the sixth lens element comprises a first side surface facing the first side and allowing imaging rays to pass through, and a second side surface facing the second side and allowing imaging rays to pass through, wherein
- the first lens element has negative refracting power;
- a periphery region of the second side surface of the second lens element is convex;
- the third lens element has positive refracting power, and a periphery region of the first side surface of the third lens element is concave;
- the fourth lens element has positive refracting power;
- and
- lens elements of the optical lens assembly only include the first lens element to the sixth lens element described above, and satisfy a following conditional expression:
- EFL/BFL≥3.800, where EFL is an effective focal length of the optical lens assembly, and BFL is a distance on the optical axis from the second side surface of the sixth lens element to a reference surface, wherein the reference surface is a light-emitting surface or an image plane.
