The last photograph in the gallery shows a page from the manufacturer's original catalogue. Arrows indicate both this exact condenser holder model and the matching condenser.

Mechanically, this condenser is mounted using a dovetail guide located beneath the microscope stage. On the Carl Zeiss Jena Ergaval this is a separate condenser mounting assembly, while on the Carl Zeiss Jena Amplival the dovetail is integrated into the microscope stage support assembly.

# Examples of use
- if you own a used microscope without a condenser
- if your microscope is equipped with a standard Abbé condenser with a numerical aperture of N.A. 1.2
- if you already have a condenser but it is damaged or of poor optical quality
- if you want to modify this condenser holder to install a dark-field condenser
- if you need components from this condenser for your own DIY projects
