Abstract
A light emission device according to the present disclosure includes: a collimated light source; a planoconvex lens having a flat surface and a convex curved surface, the planoconvex lens being configured to converge collimated light that is emitted from the collimated light source to form a convergent beam; an optical member configured to be irradiated with the convergent beam; and a housing in which the planoconvex lens is housed. The housing includes a lid configured to support the optical member, the lid having a through hole for allowing the convergent beam to pass through. The lid is in contact with at least a portion of the flat surface of the planoconvex lens.
