Unidentified "Leitz" marked items


Recommended Posts

Advertisement (gone after registration)

I still have in a drawer, with some minor remains of my Fontenelle Collection, a few items I never succeeded in identifying. Some are definitely linked to "microscopy", one for sure is part of a Metallux equipment. Would somebody have enlightened views?

Hello Pecole,

 

the 1st and 2nd picture show a darkfield condensor for a transmitted light microscope, persumably prewar manufactured or at the end of the forties.

 

The 3rd shows the connecting part (to the microscope stand) of a revolving nosepiece or similar, seems to be for an Ortholux/Metallux or a Laborlux II.

 

The item on the 4th picture I cannot identify. May it belongs to the illumination of a Metallux II but I do not know.

 

The last two pictures show a special large field vertical illuminator for reflected light darkfield microscopy. It is a part of the Ultropak System, made for different LEITZ microscopy stands like Ortholux, Orthoplan and some more with different attachment parts. The swung out part should be a polarization filter but the actuating lever ist broken. This item seems to be finished for a Laborlux I but I´m not sure.

 

Excuse my poor english

 

Best regards

 

Wolfgang

Thanks a lot, Wolfgang, and be sure your English is excellent ! You are a specialist of Leitz microscopy, aren't you ? Here is a photo of the only microscope I had in my collection - for "historical" reasons. Can you identify it ?

And many thanks again.

Hello Pierre,

 

thank you for your compliments :) . I´m not a specialist in Leitz microscopy but microscopy is a great part of my job and part of my leisure activities since more than 35 years. Over that time I have seen and learned about older and very old microscope systems and some of them found the way into my private lab.

 

I made a mistake:

Instead of Laborlux I  I meant the Dialux I (http://www.microscopy-uk.org.uk/mag/indexmag.html?http://www.microscopy-uk.org.uk/mag/artmar08/go-leitz.html), but it could also be mounted to an inverted mikroscope (Waldmann type, see below http://www.mikroskopie-forum.de)/index.php?topic=11367.0)

 

Your own old microscope, for me it seems to be a GH-Type from around the 1920th because of the design of the microscope stand, but the fine mode actuator should belong to an older type. Please have a look to this list: http://www.leitz-ortholux.de/forum/seriennummern.pdf

The text is written in german but you will detect your microscope serial number approximately.

 

If there are some more questions ....

 

Best regards

 

Wolfgang

Thanks a lot, Wolfgang. "My" microscope bears the serial number 135890 and, following the listing you were so kind as to send, is a model IV of 1912.
