Abstract
PURPOSE: To achieve the miniaturization and automation of the apparatus by using primary photo detecting sensor arrays.
CONSTITUTION: Primary photo detecting sensor arrays 13, 14 are disposed to the optical system including the lens to be examined and are connected to a signal selecting circuit 28 and timing control circuit 27. And the primary photo detecting sensor arrays 13, 14, signal selecting circuit 28 are operated by way of a timing control circuit 27 under controlling of a computer 29 to input the signals by a slit image 12 having distortions owing to the distortions of the face, striae, eccentricity, etc. of the lens to be examined having been formed in the primary photo detecting sensor arrays 13, 14 to the computer 20 via peak holding circuit 29, level comparator 32, calculation circuit 34, etc. These are then compared with the reference evaluation quantities having been obtained by measuring an ideal lens which becomes standard, whereby the optical performances of the lens to be examined are evaluated.
