Zeiss Axioskop 20 microscope manual this element can be seen in figure 4.1. In the manual, this holder is shown together with the rack, which is not part of the item offered here.

The element shown and offered here consists of:
- condenser holder (fig. 4.1)
- knob for vertical condenser adjustment (fig. 4.2)
- pin with spring (4.3)
- two condenser centering screws (4.4)

Important: although this condenser holder was removed from a Zeiss Axioskop 20 microscope, its individual components (e.g. centering screws) will most likely fit condenser holders from other Zeiss Axio models.

This element can solve the following problems:
- missing condenser holder in Zeiss Axioskop 20 microscope
- damaged condenser lifting knob
- inability to center the condenser in a Zeiss Axio microscope
- bent or broken condenser centering screw in a Zeiss Axio microscope
- missing condenser centering screw in a Zeiss Axio condenser holder

This is one of those microscope elements for which many different names are used. Among others:
- condenser holder
- condenser carrier
- condenser mount
- condenser support
- condenser stage
- condenser assembly

Note - this module DOES NOT FIT Carl Zeiss Jena Nf and Carl Zeiss Jena Lu microscopes, even though the assemblies performing the same function in those microscopes look VERY similar.

In the last photos in the gallery, I use arrows to show exactly which microscope component is being offered and where it is located in the Carl Zeiss Jena NU-2 microscope.

called Zeiss Phomi)
- Zeiss Standard WL 89
- Zeiss Universal
- Zeiss Ultraphot (although the original holder in this model is black)

This complete module consists of the following parts:
- the section with the condenser focusing knob for height adjustment, mounted onto a dovetail guide using a quick-release clamping mechanism
- the condenser holder with a toothed rack, condenser retaining screw and two centering screws
- a swing-out holder for a 32 mm round filter
- a swing-out wide field lens used to provide even illumination of the specimen when observing with low-magnification objectives

This holder accepts condensers with a dovetail mount – it is not intended for condensers with a diameter of 37 mm or 39.5 mm.

The image gallery contains detailed photographs of this part together with its dimensions.
In the last photograph, an arrow indicates where this part is located inside the microscope.

Additionally, the video gallery contains two videos: the first presents this part from different angles, in close-up views, and demonstrates the movement of its moving components, while the second video shows, among other things, how to remove this condenser holder from the microscope body using a Zeiss Photomicroscope II as an example.

The Zeiss Universal, Zeiss Ultraphot, the earliest versions of the Zeiss Standard WL, and the first model of the Zeiss Photomicroscope were originally factory-equipped with this component in black.

The Zeiss Photomicroscope II, Zeiss Photomicroscope III, and the later versions of the Zeiss Standard WL were factory-equipped with this component in grey.

The colour of this component has no effect on compatibility. In other words, a component of either colour fits all of the microscope models listed above.

The component presented here is grey.
If you're looking for the gray version, it's listed in this database under number 99606.

unscrewed. It is mounted onto the dovetail guide located underneath the microscope stage carrier and secured with a clamping screw.

Carl Zeiss Jena Ergaval microscopes were originally equipped with a condenser attached to the "MO" holder. This holder has a permanently mounted iris diaphragm and wide-field lens, while the condenser itself is screwed into the upper thread. In this configuration, the condenser cannot be exchanged.
The Carl Zeiss Jena Fluoval uses a similar arrangement, whereas the Carl Zeiss Jena Amplival was originally equipped with a panchromatic condenser.

If the user wishes to use other condensers (including those made by manufacturers other than Carl Zeiss Jena), the original condenser holder must be replaced with the MZ condenser holder. Once this has been done, any microscope condenser with a mounting diameter of 39.5 mm can be installed. Condensers with a 37 mm mounting diameter can also be used if they are fitted with a suitable adapter ring.

This is exactly such a holder for interchangeable condensers.

Basic specifications:
Manufacturer: Carl Zeiss Jena
Original documentation name and model: Kondensor-Einhänger MZ
Colour: grey, the version manufactured for the Mikroval microscope series
Internal diameter: for mounting condensers with a 39.5 mm mounting diameter (for example the Carl Zeiss Jena cardioid darkfield condenser)
Condenser retaining screw: yes, central condenser clamping screw
Centering screws: yes, two condenser centering screws
Microscope mounting: dovetail

Although this component is grey, it is also compatible with older black Carl Zeiss Jena microscopes from the 1950s and 1960s (it simply will not look completely original unless it is repainted).

This condenser holder is compatible with, among others:
- Carl Zeiss Jena Ng (black microscope)
- Carl Zeiss Jena Polmi-A (black microscope)
- Carl Zeiss Jena Nf (black microscope)
- Carl Zeiss Jena Nu (the NU-2 version is grey)
- Carl Zeiss Jena Ergaval (grey microscope)
- Carl Zeiss Jena Fluoval / Fluoval-2 (grey microscope)
- Carl Zeiss Jena Amplival and its variants (grey microscope)
- Carl Zeiss Jena Docuval (grey microscope)

Various names are used for this microscope component, including:
- condenser holder
- condenser carrier
- condenser mount
- condenser support

The last photograph includes an excerpt from the original manufacturer's documentation. An arrow indicates this exact model of condenser holder, making it easy to identify the component.
