This is description of this part:
Carl Zeiss Jena Apl 1.4 aplanatic bright-field microscope condenser complete with condenser holder and iris diaphragm.
Basic specifications:
Manufacturer: Carl Zeiss Jena
Model: Apl 1.4
Holder name according to the manufacturer's catalogue: Kondensor-Einhänger mo
Condenser name according to the manufacturer's catalogue: Aplanatischer Kondensor 1.4 mo / ms
Version: grey version from a Carl Zeiss Jena Ergaval microscope (as opposed to the black version used, for example, on Carl Zeiss Jena Nf microscopes)
Numerical aperture N.A.: 1.4
Aperture diaphragm: yes, mounted in the condenser holder
Wide-field lens: yes, swing-out type
Removable top lens: yes, unscrewable
Mounting diameter: the optical section (the condenser without the iris diaphragm) has a mounting diameter of 39.5 mm and can be unscrewed from the condenser holder

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.
What is this part needed for?
- 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
