509 Microscope Type II
Pied en fer à cheval évasé. Un support de platine à trois branches est fixé sur le pied. Le corps du microscope pivote à 180 ° autour de son axe.
La mise au point macrométrique se fait par tirage du tube. La mise au point micrométrique s’effectue par le biais d’un bouton se trouvant sous la colonne. Le condenseur est fixé dans une coulisse escamotable sous la platine.
Le miroir est plan concave, articulé dans tous les sens.2 valets
LA PARTICULARITE DE CET APPAREIL EST D’AVOIR LA MEME FIXATION DU TUBE VERTICAL QUE LES MICROSCOPES KELLNER. VIS FRONTALE SERRANT LE FOURREAU. IL S’AGIT PROBABLEMENT D’UN DES DERNIERS MODELE STYLE KELLNER.
Il s’agit également d’un des derniers microscopes (vers le numero 1500 source Schwartz Thomas) avec des objectifs à pas de vis externes. A partir environ du numéro 1500 , les pas de vis sont internes.
