  • Optical device, optical test bench and optical test method
    Patent number: 9719882
    Abstract: This optical system includes: a device (106) for generating a plane light wave, called a collimated light wave (OLcol); and a device (114) for deviating the collimated light wave so as to provide a light wave, called a test light wave (OLtest), the deviating device (114) having an adjustable focal length.
    Type: Grant

  • Test object used for projecting a set of marks to infinity
    Patent number: 8254032
    Abstract: The collimated test object according to the invention is used for projecting to infinity a set of marks, the positions of which are very accurately known so as to be able to verify the alignment and/or the distortion of optical equipment such as sensors or collimated screens. This test object comprises a plurality of microcollimated sets, each comprising a light source, an elementary test object comprising a mark illuminated by the source as well as a collimation lens for projecting the mark to infinity. With this solution, one gets free of aberration problems to which are subject convention test objects of large dimensions.

  • Method of treatment of a mixture of air and at least partially radioactive rare gases
    Patent number: 4055625
    Abstract: The method of treatment of a mixture of air and at least partially radioactive gases such as xenon and krypton in particular, especially gaseous effluents derived from the reprocessing of irradiated nuclear fuels, comprises a stage of concentration of the rare gases in solution in liquid oxygen by cryogenic distillation of the light gases and especially nitrogen from the liquefied mixture.
