Abstract (en)
[origin: WO2019179841A1] The present invention relates to a lighting device (1, 100) for an imaging system having an imaging lens (2), comprising: a sleeve (10) configured to be positioned around said imaging lens (2); at least one optical fibre (14) rigidly connected to said sleeve (10) and arranged to guide light coming from at least one light source; and a directing means (17, 17') configured to orient a light beam emitted by the at least one optical fibre (14) so as to light a field of view of the imaging system along a lighting axis forming an angle relative to the optical axis of the lens (2) that is larger than the numerical aperture of the imaging system. The invention also relates to an imaging system using this device.
