Abstract
The utility model discloses a detecting apparatus for progressive multi-focal point glasses, which takes advantage of a parallel monochromic light source apparatus connected to a light-spot matrix encoder and radiating vertical parallel monochromic light beams through light passing apertures of to-be-detected progressive multi-focal point glasses. Divided by plural light holes on the light-spot matrix encoder, the light beams are turned into thinner parallel light beams, which form a light-spot matrix on the planar array imaging sensor when reaching the projection points of the to-be-detected progressive multi-focal point glasses; controlled by a master control circuit board, the light-spot matrix encoder calculates the diopter at each projection point of the to-be-detected progressive multi-focal point glasses based on the light spots on the light spot matrix and on the position movements of the light holes corresponding to the light spots. The detecting apparatus of the utility model has a simple and well-designed structure, and innovates the prior art by enabling detections not just to be based on limited number of selected light spots, which can fully detect the diopter of progressive multi-focal point glasses with only one time.
