摘要
An externally dimensional - measuring device includes a light source; an optical system, consisting of the light emitted by the light source is focused on an optical axis; a reflector which reflects the focused light; a detector, which detects an intensity of the reflected light; and a computing device in which an external dimension of a measured object using a first focus position, a second focus position and a position of the reflector on the optical axis is calculated, wherein the first focus position is located on the optical axis, where a tip in a light intensity reflected by the detector for light is detected, which is reflected by a first surface, and wherein the second focus position is located on the optical axis, where a tip in a light intensity reflected by the detector for light is detected, which is reflected by the reflector and at a second surface was emitted.
