Abstract:
An optical lens, which acts on the light emitted from a semiconductor laser element comprising an array of a plurality of light emitting components, and then emits the light, comprising:two first optical member arrays each having a plurality of columnar optical members including first optical action components in the side surface of the columnar optical member that have a curved surface on either the incident light side or the emitted light side and that act on the light emitted from the light emitting components, the columnar optical members being disposed in parallel and in the same plane; and a second optical member that is columnar in shape and made of a transparent material, and inside of which the two first optical member arrays are embedded in parallel in the columnar axial direction thereof, wherein the columnar axial direction of the columnar optical members is inclined by &agr;Â° with respect to the direction in which the light emitting components are arrayed in the semiconductor laser element, the material of which the columnar optical members are made has a refractive index that is different from that of the transparent material of the second optical member, and each of he columnar optical members has two end portions both of which are exposed from the second optical member.
