Abstract:
A gas detector including: an assembly of two coaxial parabolic reflective caps having opposite concavities, and a wafer arranged in the focal plane of the two caps, at the center of this focal plane, comprising, back-to-back: a diverging light emitter directed towards the first cap and a light receiver directed towards the second cap, wherein the two caps are distant substantially by the sum of their focal distances plus the thickness of the wafer.
