Optical device producing two beams capable of reaching a common sensor
First Claim
1. An Optical device comprising a reflecting element arranged on the optical path of an incident beam emitted by a first optical source so as to form a reflected light beam, and a second optical source producing a second light beam of different wavelength so that the reflected beam and the second light beam pass through a zone of the space wherein an object to be analyzed is to be exposed, and reach a common sensor, wherein the reflecting element is arranged proximate to and outside the optical path of the second beam and wherein the optical device comprises a collimating lens common to the first and second sources and arranged at an intersection of the first incident beam and of the second beam.

Abstract
The optical device comprises a first and a second optical sources respectively emitting a first incident beam and a second light beam of different wavelength. Reflecting means, which may be a mirror, are arranged on the optical path of the first incident beam so as to form a reflected light beam. The reflecting means are arranged outside and proximate to the optical path of the second light beam so that the reflected beam and the second light beam pass through a zone of the space, wherein an object to be analyzed is to be exposed, and reach a common sensor.
