| Summary: | A shape measuring apparatus includes a point light source including a white light-emitting diode, a collimator lens for forming a parallel beam as a result of causing light emitted from the point light source to be incident upon the collimator lens, a telecentric lens device, including two-side telecentric optics or object-side telecentric optics, for being irradiated with the light that has passed an object to be measured from the collimator lens, and an image sensor for projecting thereon an image of the object produced by the light that has passed through the telecentric lens device. |
