  • Patent number: 11609184
    Abstract: An apparatus for characterizing luminescent entities by excitation comprising: • a substrate (6) being in contact with a solution comprising luminescent entities; • a source of electromagnetic radiation (4) providing at least a primary beam of radiation (8); an objective (5); a first optical element (1) capable of transforming the intensity profile of the primary beam (8) into an arbitrary secondary intensity profile (distribution) (9); a second optical element (2) capable of separating (discriminating) radiation by wavelength; and a detector (7), where the arbitrary secondary intensity profile has at least an off-center circular continuous intensity distribution (33) focused on the back focal plane (12) of the objective forming a collimated beam (10) capable of creating an evanescent field on the side of the substrate where the solution comprising luminescent entities are located, where the evanescent field excites the luminescent entities thereby creating emission radiation separated by the second optical e
