Summary:A object lens producing device for producing an object lens consisting of a plurality of lenses and having a numerical aperture of not less than 0.7, the device comprising a positioning mechanism 31 for determining the relative position between the lenses in such a manner that with respect to a cylindrical lens holder 3 of synthetic resin material having one lens 1 fixedly attached thereto, the other lens 2 is positioned on the basis of the one lens and fixed with respect to the lens holder. L'invention concerne un dispositif de production de lentille-objet conçu pour produire une lentille-objet consistant en une pluralité de lentilles et possédant une ouverture numérique d'au moins 0,7. Ledit dispositif comporte un mécanisme de positionnement (31) conçu pour déterminer la position relative entre les lentilles, de sorte que, par rapport à un porte-lentille cylindrique (39) en résine synthétique auquel une lentille (1) est fixée, l'autre lentille (2) est positionnée par rapport à l'autre et fixée par rapport au porte-lentille.
