Abstract:
The present disclosure relates to an apparatus for inspecting alignment of optical device including: an optical device comprising a housing having an optical path of the shape of a cylinder, a light source disposed inside the housing to provide an illumination light for inspection to a subject surface, and a collimating lens for converting the illumination light irradiated from the light source into a parallel light beam; and an alignment evaluator that is provided with a condensing lens for converting the parallel light beam into a focused light beam, and that is disposed in front of the optical device.
