Titel: JENAVAL und objektiv 1x
Beitrag von: marian.szewczyk in Januar 13, 2016, 15:34:53 NACHMITTAGS
Hello,

First of all, I would like to thank you to everyone that will try to help me. Recently I bought lens (GF-Planachromat 1x/0,03 spez/-A) for my Jenaval microscope. The problem is I am unable to focus on object with this lens. I attach the picture of my microscope setup. Do you have any ideas how to solve that problem?

Moin,

Ich vermute Sie brauchen noch eine zusätzliches Linsenelement welches Sie oberhalb des Objektives einschieben müssen.

Gruss

Hello,

For the 1x to work, you require a special ("spez") tube lens in the microscope head (tube lens "1/1,6") that is used just for this objective and the 1,6x.

This special tube lens has to be mounted on a magnification changer, like the one on the "Jenamed Histology" microscope  http://interphako.at/PDF/jenamed.pdf or the Jenaval (Fig. 1/4: www.mikroskop-online.de/Mikroskop%20BDA/30-0020a.G%20%20Mikroskop%20JENAVAL%20(B).pdf ) or in the Kontrast-Tubus (Fig. 4/41)

If you don't have that magnification changer with 1/1,6 tube lens, unfortunately, you won't be able to use this objectice, as far as I know. If you find that tube lens, it can be retro-fitted into the magnification changer.

Kind regards,

Jon
