Abstract
An optical lens includes a lens portion having an optical axis, and an exterior portion connected to an outer periphery of the lens portion. The exterior portion has first and second surfaces that are disposed along a direction parallel to the optical axis and spaced apart from each other, a first annular surface that extends from a periphery of the second surface parallelly with respect to the optical axis, and a second annular surface that interconnects the first annular surface and the first surface. The second annular surface extends obliquely with respect to the first annular surface.
