    摘要: A plastic lens includes a lens body having effective optical diameter and is mounted in a lens mount by a hold ring which is threaded in the mount. Thin portion is formed outside the lens body and is thinner than minimum thickness of the lens body; end portion is formed outside from and thicker than the thin portion and is adapted to secure the lens with the lens mount and the hold ring. The thin portion absorbs heat stress caused by linear elongation coefficient difference between plastic lens and aluminum lens mount.
