Optical device having an optical lens and a mounting assembly

摘要

An optical device comprises an optical lens and a mounting assembly for securing the optical lens to a support surface. The optical lens has a longitudinal axis and has first and second projections; the mounting assembly includes a clamp member which has a clamp surface and depresses the optical lens downwardly through contact of the clamp surface with the optical lens so as to mount the optical lens on the support surface. The clamp member is formed, on the clamp surface, with first and second holes engageable with the first and second projections of the optical lens, respectively; the second hole is an elongated opening extending in the longitudinal direction of the optical lens.
