OPTICAL LENS

摘要

PURPOSE: An optical lens is provided to minimize the compressive deformation of the effective efface while applying uniform pressure on the isotropy effective face. CONSTITUTION: An optical lens(100) comprises an effective face(110) and a rib(120). The light is projected on the effective face. The rib is extended to the outside of the effective face. The rib has a barrel contact surface. The barrel contact transfers an external force on the outside in axially symmetrical in relation to the optical axis of the effective face.
