# Part manufacturer:
Carl Zeiss Jena

# Full manufacturer name:
VEB Carl Zeiss Jena DDR (former East Germany)

# Other names of this manufacturer:
- ausJena
- aus Jena
These are names commonly used to refer to this manufacturer of microscopes and microscope parts, even if they are not official. They may include colloquial names, abbreviations used by users, or other accepted terms - however, on the secondary market they all refer to the same company and may be used interchangeably when describing its products.

# Belongs to category:
Condensers

# Description and specifications:
Aplanatic low numerical aperture condenser for the Carl Zeiss Jena Jenaval microscope.

Carl Zeiss Jena Jenaval and Jenalumar microscopes each have two condensers - a low-power survey condenser with low numerical aperture and a main condenser with high aperture. Both sit on a common carrier at the same time, which lets you switch between them. What I am offering here is the condenser alone, so without the carrier.

Parameters of this condenser:
Manufacturer: Carl Zeiss Jena
Numerical aperture N.A.: 0.12
Correction: aplanatic
Mounting: the condenser screws into a dedicated carrier. The thread diameter is 36 mm.
Iris diaphragm: yes, the condenser has a ring that opens and closes the diaphragm
Removable top lens: no
Intended use: this condenser model was fitted in Carl Zeiss Jena Jenaval microscopes

This condenser can also be screwed into the carrier of Carl Zeiss Jena Jenalumar microscopes - it is the same carrier as in Jenaval microscopes. Note, however, that Jenalumar microscopes came with a 0.20 N.A. condenser as standard (you can see it here: https://www.microscopeparts.eu/part/00530).

A condenser with such a low numerical aperture is intended for observation with low magnification microscope objectives (1.25x / 3.2x / 6.3x, 10x at most).

# Examples of use
- if this condenser is missing from your Carl Zeiss Jena Jenaval microscope, because someone unscrewed it, for example
- if you have a microscope with this condenser but it is damaged - the diaphragm blades are bent or broken, for instance
- if you have a Carl Zeiss Jena Jenalumar microscope and deliberately want to fit a 0.12 N.A. condenser in it
- if you want to use this condenser as the only condenser in a different microscope and mount it there with your own DIY holder
