Abstract

PURPOSE:To permit accurate measurement regardless of positions of a matter by using a parallel light beam obtained through a linear light source and a collimator lens in an optical gauge for measuring outer diameters. CONSTITUTION:A collimator lens 2 is disposed in front of a linear filament light source 10 at a position spaced therefrom by a distance of focal length (f). A light from the light source is turned to a prallel beam through the lens 2. An optical image formed on an image sensor 4 via an aperture slit 3 is dimmed in its part where the beam is interrupted by a bar-like body. Due to use of the parallel light beam in place of a diffusion light from a point light source, there can be eliminated such a need that the material has to be disposed within the depth of focus of the lens, or such a defect that magnification is varied dependent on focus positions.
