ABSTRACT:
A lens is fitted into a metal ring that covers the outer peripheral surface of the lens and can be soldered to a fixture member. The side cylindrical part of the metal ring is expanded toward the outer peripheral direction thereof by the pressure of the optical material put inside it, and, thus expanded, it defines the final dimension of the metal ring. One of the two openings formed on both sides of the side cylindrical part of the metal ring is so designed as to have a curving cylindrical part that extends from the side cylindrical part, and this curving cylindrical part is folded toward the optical functional face of the optical device to construct a metal ring-fitted optical device.
