摘要： An optical component bowing device includes a bending moment generating structure. In a particular embodiment, the bending moment generating structure can have extension members that extend in a direction substantially orthogonal to a longitudinal direction of an optical component. The extension members can be positioned adjacent longitudinal end portions of the optical component. The bending moment generating structure can also have loading members that load the extension members in a direction that is parallel to a longitudinal direction of the optical component, whereby displacement of the extension members can generate a bending moment in a supported portion of the optical component that reflects or shapes a light beam. The bending moment generating structure can also include a reflective surface. Extension members on at least one end of the optical component can be T-shaped when seen in plan view in a direction orthogonal to the reflective surface.
