Optical assembly and corresponding illumination device

摘要

This optical assembly comprises a securing support ( 40 ), an optical focusing element ( 44 ) and a reflecting mirror ( 42 ) which is suitable for reflecting an incident light beam (F 1 ) towards the optical focusing element ( 44 ) in order to focus it onto an illumination plane (P). The reflecting mirror ( 42 ) is movable relative to the securing support ( 40 ). The optical focusing element ( 44 ) is movable relative to the securing support ( 40 ). The assembly includes elements for connecting the focusing element ( 44 ) to the mirror ( 42 ) for synchronised displacement of the two of them. The assembly is useful in devices for illuminating operating fields.
