Abstract

Process for the production of a device for the optical analysis of a microparticle flux and application to the production of a cytofluorimeter. As microparticles are able to emit light, around a nozzle (4) made from a material transparent to said light and whose hole (8) is provided for the passage of the flux, is moulded an optical element (6) made from a material transparent to said light, which has a melting point below that of the material of the nozzle and which has an optical index close to that of said material, and which has a dioptric element (10) admitting an optical axis passing through the hole. The cytofluorimeter in particular incorporates the device (2) obtained by this process.
