Abstract

PURPOSE:To make it possible to measure accurately at a close position the main optical axis of a headlight by displaying at a short distance the illumination distribution from a headlight that is given at a distance far away using a light collecting lens. CONSTITUTION:A light collecting lens 4 is provided in front of a light receiving mechanism 2 for collecting a headlight beam 1 to obtain a illumination distribution at or near the focus of the light collecting lens 4 that is similar to the illumination distribution at a position that is far, for instance at 10m, from the headlight 1, by arranging a light receiving mechanism 2 against the illumination distribution near the lens 4 the measurement with the same results as by arranging the light receiving mechanism 2 at the far position becomes possible.
