A method and apparatus for measuring an optical property of an optical device by locating a main converging lens (22) in front of an optical measuring system (20) capable of measuring collimation, and locating a carrier, including an auxiliary converging lens (24), first at a position wherein the back focal plane of the auxiliary converging lens (24) coincides with the front local plane of the main converging lens (22) and the optical device to be tested is located on the carrier in the front focal plane of the auxiliary converging lens (24), and then at a position wherein the beam reflected back to the optical measuring system (20) via the auxiliary converging lens (24) and main converging lens (22) is found by the optical measuring system to be collimated. <IMAGE> |
