Abstract
PURPOSE:To provide an apparatus for inspecting glass bottles or the like, in which a glass bottle is placed at the front focal point of a convex lens and laser beam is irradiated on the bottle, can be achieved, promptly and unintendedly, by detecting the strength of laser beam transmitted through a space filter disposed at the rear focal point of said convex lens.
