Carl Zeiss Jena Nf / Nu polarisation stage holder (Pol stage support)

The name of this microscope part.

Carl Zeiss Jena - centerable polarizing stage holder for Carl Zeiss Jena Nu / Nu2 / Nf microscopes

Description of this part for the microscope.

This microscope stage holder fits the following Carl Zeiss Jena microscopes:
- Nf
- Nf with EPI / EPI POL reflected light illuminator
- NU
- ...

NU2

This holder features two centering screws on the side, which are very important for polarization. The front retaining screw is also different from standard microscope stage holders (i.e., those without centering). Of course, standard stages, rectangular, round, and sliding EPI stages can also be used with this holder.

Carl Zeiss Jena Nf / NU microscope oblique illumination sliding iris diaphragm

The name of this microscope part.

Carl Zeiss Jena Nf / NU microscope oblique illumination sliding iris diaphragm

Description of this part for the microscope.

Iris diaphragm module for Carl Zeiss Jena Nf, NU and NU-2 microscopes.

In the following microscopes:
- Carl Zeiss Jena Nf
- Carl Zeiss Jena NU and NU- ...

2

this module serves as the aperture diaphragm. The field diaphragm is built into the illumination path inside the microscope base.

At the same time, it provides a holder for 32 mm round filters. The video available in the gallery also demonstrates how a filter is inserted into this holder.

The sliding iris diaphragm mounted beneath the microscope condenser allows oblique illumination to be set, producing a three-dimensional image with enhanced contrast of transparent specimens (such as unstained cells). The resulting image is similar to differential interference contrast (DIC).

This component is known under various names, including:
- decenterable iris diaphragm
- decentering aperture diaphragm
- off-axis iris diaphragm
- eccentric iris diaphragm
- sliding iris diaphragm
- sliding iris
- oblique illumination condenser
- condenser with sliding iris
- oblique illumination module
- oblique illumination diaphragm
- offset iris
- Poor Man's DIC device

Note — this diaphragm DOES NOT FIT the Carl Zeiss Jena Lumipan microscope, even though it appears very similar at first glance.

Because this module is removable, it is missing from a large proportion of microscopes available on the second-hand market. During decades of use, these diaphragm modules were frequently lost.

In addition, they are often damaged and need replacement. The most common failures include:
- the protective glass covering the diaphragm becomes scratched or broken
- the diaphragm blades become bent or broken
- the screw used to decenter the diaphragm bends or breaks
- the return spring responsible for restoring the diaphragm to its centred position becomes damaged or is missing

Replacing the damaged assembly with the diaphragm module offered here solves these problems.

Carl Zeiss Jena Ng / Nf microscope condenser holder model MZ

The name of this microscope part.

Carl Zeiss Jena Ng / Nf microscope condenser holder model MZ

Description of this part for the microscope.

Holder for mounting interchangeable microscope condensers for Carl Zeiss Jena microscopes.

This MZ condenser holder is a separate, removable module that can be ...

unscrewed. It is mounted onto a dovetail guide located underneath the microscope stage carrier. The condenser holder is secured to the guide with a clamping screw.

It can accommodate any microscope condenser with a mounting diameter of 39.5 mm, regardless of the manufacturer. Condensers with a 37 mm mounting diameter can also be used if they are fitted with a suitable adapter ring.

Basic specifications:
Manufacturer: Carl Zeiss Jena
Original documentation name and model: Kondensor-Einhänger MZ
Colour: black, the version manufactured for the black Carl Zeiss Jena microscopes from the 1950s and 1960s
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 microscope component is black, it is also compatible with the newer grey Carl Zeiss Jena microscopes of the Mikroval series.

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 the condenser holder, making it easy to identify the component.
