OPTICAL HEAD FOR PERFORMING AN ATMOSPHERIC MEASUREMENT, AND RELATED SYSTEM AND MANUFACTURING METHOD

摘要

The invention relates to an optical head (1) for performing an atmospheric measurement, which is capable of receiving at least one pair consisting of a refractive optical system (23) and an optical fibre for transmission and reception. The optical head is made in a single piece and so as to be rigid, and includes at least one recess (2") for receiving at least one element from among a refractive optical system (23) and an optical fibre for transmission and reception, said recess (2") being formed by an outer shell (3) that comprises a first composition consisting of a rigid, athermal composite material, and inside which is attached at least one metal adjustment insert (4) that forms a support for one element from among the refractive optical system (23) and the optical fibre for transmission and reception, and comprises a second composition that can be more easily machined than the first composition and is machined so as to ensure that the optical axis (50) of the refractive optical system (23) and the axis of the output beam of the optical fibre for transmission and reception coincide along a single axis, and so as to ensure the positioning of said single axis relative to a reference axis. The invention also relates to a related system and manufacturing method.
