Abstract
A lens structure includes a lens barrel, a first lens and an opaque layer. The lens barrel has an axially-extended accommodation space. The first lens includes a surface and is disposed in the accommodation space, wherein the surface includes a light penetrating zone, and the light penetrating zone includes an optical axis passing through a center of the first lens. The opaque layer is formed on the surface and disposed between the light penetrating zone and the lens barrel. The lens structure satisfies: 0.2≤R/HO≤0.8, wherein R is an effective radius of the first lens, and HO is half of an outer diameter of the first lens.
