Title (EN) ACHROMATIC ANASTIGMATIC ANAMORPHIC PROJECTION OBJECTIVE FOR FOCUSING LASER BEAMS
(FR) OBJECTIF DE PROJECTION ANAMORPHOSEUR ANASTIGMATIQUE ACHROMATIQUE PERMETTANT DE CONCENTRER DES FAISCEAUX LASER
Abstract:
(EN) In a flow cytometer, an objective lens (20) focuses in a common plane (P) an input laser-beam having four different wavelengths. The objective (20) consists of three single-lenses (CL1, CL2, FFL), the two first ones (CL1, CL2) being cylindrical for shaping and reducing the size of the input laser-beam, the third one (FFL) being spherical to focus the reduced-size laser-beam in the common plane (P).
(FR) Selon la présente invention, dans un cytomètre en flux, un objectif (20) concentre dans un plan commun (P) un faisceau laser d'entrée ayant quatre longueurs d'onde différentes. L'objectif (20) est constitué de trois lentilles uniques (CL1, CL2, FFL), les deux premières (CL1, CL2) étant cylindriques pour la mise en forme et la réduction de la taille du faisceau laser d'entrée, la troisième (FFL) étant sphérique pour concentrer le faisceau laser de taille réduite dans le plan commun (P).
