Abstract
A method is disclosed for manufacturing a lens array optical system including a flat glass plate and lenses each of which has a flat surface and a curved surface. The method includes the steps of removably fixing each lens with a first adhesive agent to a lens holder having lens holding portions corresponding to the curved surfaces of the lenses, polishing the flat surface of the lenses and the lens holder so that the polished flat surface of the lenses are flush with a polished flat surface of the lens holder, fixing the lenses to said flat glass plate with a second adhesive agent by pressing the lenses against the flat glass plate and hardening the second adhesive agent, and removing the lens holder from the lenses.
