Zusammenfassung:	PURPOSE: To contrive promptness and exactness to determine whether or not a machined lens agrees to prescribed data by inputting the optical characteristic value of the machined lens to compare with the prescribed data. CONSTITUTION: An installing protruded part 14 is interposed above a lens cradle 13. A sucker installing lever 16 serving as machining jig-installing means is horizontally and rotationably and vertically and drivably mounted on the lower part of the protruded part 14 centered with respect to an axis A-A'. A sucker holder 17 is provided on the intermediate part of the sucker installing lever 16 to demountably hold the installing shaft 18a of a sucker 18 made of rubber serving as a machining jig. Now, a machined lens L is mounted on a cradle 13 to measure the optical characteristics of the optical center of the lens L. Comparison is made to already inputted prescribed lens data on spherical degree, cylindrical degree. The messages are displayed on a TV screen. Thus, determination is made whether or not the optical characteristics of the machined lens L agree to the inputted prescribed data to display on the screen. Thus, determination on the machined lens L and the prescribed data are promptly and exactly done.
