Abstract

PURPOSE:To perform inspection efficiently by providing a light source movable in the direction (z) and a chart plate rotatable within a horizontal plane above the lens array movable in the directions (x) and (y) within a horizontal plane and also providing a solid scanning element capable of movement and rotation within a horizontal plane below the array. CONSTITUTION:The shading direction of the rectangular-wave chart 46 and the longitudinal direction of the solid scanning element 52 are set in the direction (y) within a horizontal plane and adjustment is made by rotating knobs 58a, 59a, 59b, 60a, etc. so that an image of the rectangular-wave chart 46 made by a light source 51 is formed on the solid scanning element 52. A step motor 170 being driven, the lens array 2 to be inspected located on a moving block 14 is moved bit by bit in the direction (x) and the distribution of luminous energy is detected by a scanning element array. By subjecting a detection signal thus obtained to operation processing in an operation circuit, MFT can be inspected. Moreover, by rotating the rectangular-wave chart 46 within a horizontal plane by means of a lever 50, MFT in each direction can be inspected. In this way, the inspection can be carried out efficiently.
