# 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.

# Belongs to category:
Illuminators

# Description and specifications:
Halogen lamp (bulb) holder for Carl Zeiss Jena Ergaval and Amplival microscopes (including their variants).

NOTE - VERY IMPORTANT: it is not the case that having a CZJ Ergaval / Amplival microscope with a classic illuminator (6V 15W filament bulb) and simply replacing the bulb holder with the one offered here will create a halogen-illuminated microscope. No.
- the original holder of the "regular" bulb contains a lens that collimates the light beam
- the halogen bulb holder does not contain that lens
- Ergaval / Amplival microscopes designed for halogen illumination have an additional lens threaded into the base

Halogen illumination is (according to many experts) the best microscope illumination because it delivers strong light with a full spectrum, whereas LED often provides only a portion of the color spectrum.

Other used names:
- illuminator
- halogen lamp
- bulb holder
- lamp housing

# Examples of use
- if you own a microscope in which the illuminator is missing, which is often the case when purchasing such an old microscope
- as a service part when it is necessary to replace an existing, broken illuminator
- if you are deliberately converting your microscope to newer illumination
- if you have a microscope with such an illuminator but need a second one to experiment with other light sources and want to switch them quickly
