# 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:
This microscope condenser enables operation in polarized transmitted light.

Main features and parameters:
Manufacturer: Carl Zeiss Jena
Type: condenser for polarized transmitted light with the possibility of use as a brightfield condenser
Mounting: the condenser is permanently integrated with a dovetail mount
Top lens: flip-out system allowing the upper lens to be moved into or out of the optical path to change the numerical aperture
Iris diaphragm: yes
Diffuser: yes, with the possibility of moving it into or out of the optical path
Polarizer: yes, rotatable, with the possibility of moving it into or out of the optical path

This condenser fits the following Carl Zeiss Jena microscope models:
- Polmi-A
- Nf
- Ng
- Nu / Nu2

Note: despite the visual similarity of the mounting interface, this condenser does NOT fit the Carl Zeiss Jena Lu microscope.

Important: the condenser is permanently integrated with the dovetail mount and cannot be used with other microscopes without significant modifications.

# Examples of use
- as a service replacement for the entire unit if such a condenser is installed but one of its main components is damaged or in very poor condition
- if your microscope has a brightfield condenser and you want to add the possibility of working with polarized light
- if your microscope does not have a condenser, as the unit described here can also function as a standard brightfield condenser

# Removed from microscope:
