Patent ID: 8873124

Claim:
An integral plastic optical element for focusing light on a target, comprising: a first lens including an incident surface, a projection surface opposite the incident surface, and a first non-optical surface through which a light beam does not pass, the first non-optical surface including a non-transfer portion; and a second lens, integrally formed with the first lens, and including an incident surface, a projection surface opposite the incident surface, and a second non-optical surface through which a light beam does not pass, the non-optical surface including a non-transfer portion disposed opposite the non-optical surface of the first lens, wherein the first and second non-optical surfaces are on opposite side surfaces of the integral plastic optical element and the non-transfer portions of the first lens and the second lens are portions on which no surface is transferred from a surface of a mold used to form the integral plastic optical element, and at least one light beam passes from the incident surface to the projection surface of each of the first lens and the second lens.
