Abstract:
1. An optical apparatus comprising: an optical member that transmits laser light; a holding member that holds the optical member and generates heat when irradiated with the laser light; a thermomelting member, which transmits the laser light and increases adhesiveness when heated, disposed between the optical member and the holding member; and a spacing adjustment member, which transmits the laser light, disposed between the thermomelting member and the holding member, wherein the spacing adjustment member has a thickness that achieves a desired spacing between the optical member and the holding member, wherein the laser light is transmitted through the optical member, the thermomelting member, and the spacing adjustment member to irradiate the holding member, wherein a weld portion welding the spacing adjustment member and the holding member is formed therebetween, by the heat generated at the holding member, and wherein the adhesiveness of the thermomelting member is increased by the heat generated at the holding member and transmitted to the thermomelting member via the spacing adjustment member to join the optical member and the spacing adjustment member together.
