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 5-pos. RMS microscope objective turret / nosepiece / revolver for Nf, Lg, Lumipan microscope

The name of this microscope part.

Carl Zeiss Jena - objective turret for Nf, Lg, Lumipan microscope, 5 positions, RMS thread / nosepiece / revolver

Description of this part for the microscope.

I offer a black, 5-position Carl Zeiss Jena objective turret for Lumipan, Nf, Ng, Lg, and other microscopes.

Why is it a must-have?

Vintage, ...

black Carl Zeiss Jena microscopes
- Nf
- Ng
- Lg
- Lr
- Lu
- Lumipan

as well as newer, gray Carl Zeiss Jena
- Ergaval
- Amplival
- Fluoval
- Epival
- Interphako
- Vertival
- and other variants

and
- Lomo Biolam
- Bresser Biolam
- Lomo MBB-1A
- and some IOR Bucuresti

have an interchangeable objective turret.

This is an excellent solution for owning, using, and quickly replacing entire sets of objectives.

For example, you can have separate turrets already equipped with a complete set of objectives:
- low magnification for observing macro objects with side illumination, without a cover glass (e.g., 2.5x / 3.2x / 5x / 8x / 10x)
- for phase contrast
- for various phase contrasts (positive, anoptral, amplitude, Zernike)
- for DIC
- for water immersion (e.g., Lomo)
- all for oil immersion (e.g., Leitz 10x Oil / 25x Oil / 40x Oil / 100x Oil)
- apochromatic for better color
- for polarization
- only high magnifications, e.g., for analyzing cell wall ornamentation (50x / 63x / 80x / 100x)
- for darkfield work (objectives with an iris diaphragm in the center)

Therefore, having only one microscope we can use it for different purposes and not screw in and unscrew all the lenses manually each time.

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.
