Abstract

A gas sensor (20) comprising a substrate (231); an objective (211) situated on the substrate (231), adapted to collect a light beam (212, 213) emitted by a light source (210); an eyepiece (250) situated on the substrate (231), adapted to collect an incident light beam to focus it on a detector (251); return reflective surfaces (281, 282), situated facing said substrate; and at least one field lens (221), arranged on an intermediate reflective surface (222) formed on the substrate (231), and adapted to deviate the rays (213) of the light beam emitted by the light source, to bring them closer to the optical axis of the eyepiece (250).
