摘要： A plastic optical element for focusing light to a target includes a first lens and a second lens. The first lens includes an incident surface, a projection surface opposite the incident surface, and a non-optical surface through which light does not pass and that includes a non-transfer portion. At least one light beam passes from the incident surface to the projection surface. The second lens includes an incident surface, a projection surface opposite the incident surface, and a non-optical surface through which light does not pass and that includes a non-transfer portion disposed opposite the non-optical surface of the first lens. At least one light beam passes from the incident surface to the projection surface. 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 plastic optical element.

摘要： An optical scanning device for guiding a light beam to a member to scan the member with the light beam, including a light source emitting the light beam; a light deflector deflecting the light beam; a focusing optical system including a plastic optical element molded using a die. The optical element has least two transfer surfaces formed by contacting with transfer surfaces of the die and including a light entrance surface and a light exit surface; and a third surface including a non-transfer surface formed without contacting a transfer surface of the die. The light beam passes through the optical element in such a manner that the optical axis center of the light beam extends in a direction parallel to the shorter side of the optical element while being shifted from the dimensional center of the optical element toward the third surface of the optical element.
