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:
Illuminators

# Description and specifications:
Lampholder with a collimator lens for Carl Zeiss Jena Ergaval and Amplival microscopes (including their variants).

Note - VERY IMPORTANT: this is an element for an incandescent lamp illuminator. This lampholder is not required if you have a microscope with the original halogen illuminator - in that case, the collimator lens is a separate element mounted next to the field diaphragm.

Other used names:
- lamp holder
- lamp tube
- lamp support
- sometimes the German-language term "Lampenhaus" is used

# Examples of use
- if you own a microscope in which the  element is missing, which is often the case when purchasing a used microscope
- as a service part, when the existing, broken Mikroskopelement needs to be replaced
- if you are deliberately modifying the microscope illumination and need this element
