Abstract

A telecentric optical apparatus that is capable of suppressing an increase in the number of components as well as achieving high precision optical axis alignment, is provided. The telecentric optical apparatus of the present invention is characterized in that it is provided with: a first telecentric lens surface that is provided on an object side; a second telecentric lens surface that is provided on an image side and that shares a focus position with the first telecentric lens surface; and an optical path trimming part that is provided, between the first telecentric lens surface and the second telecentric lens surface, in an outside region, which is located on a side further out than a light passing region having a center thereof located at the focus position, and that changes an optical path such that a light beam incident on the outside region is prevented from contributing to image formation.
