Description of this part for the microscope.

microscope was equipped with objective nosepieces featuring a glossy surface (it may be described as a mirror-like surface). Newer Zetopan microscopes have matte nosepieces (they may be described as silver or gray). Here I present and offer a newer matte (gray) nosepiece.

Information from the manufacturer's English-language catalogue "Zetopan Research Microscope. Price List, Effective December 1, 1976":
- Catalogue number of this part: 9 03 12 05
- English name of this part: Quadruple nosepiece, on slider

When new Reichert Austria Zetopan microscopes were purchased with additional equipment (phase contrast or fluorescence), the manufacturer often supplied the microscope from the factory with two or three nosepieces (for example a dedicated nosepiece fitted with phase contrast objectives) - even 6-position versions!

The objective positions originally installed in each thread are engraved on the nosepiece presented here: 4 / 10 / 40 / 63. This is only a recommendation and any objectives may be screwed into these positions.

Important: the visually very similar black Reichert Neozet microscope uses a DIFFERENT objective nosepiece mounting system. The nosepiece from the Reichert Zetopan microscope is not compatible with the Reichert Neozet microscope.

Why is this the microscope part that every user should own in several examples?

Reichert Zetopan microscopes - both the older black models, the silver models and the latest cream-colored models - feature an interchangeable objective nosepiece. This is an excellent solution that allows complete sets of objectives to be owned, used and exchanged very quickly.

For example, you may have separate nosepieces already fitted with objectives:
- a set of low magnification objectives for observing macro objects with side illumination and without a cover glass (for example 2.5x / 3.2x / 5x / 8x)
- a complete set of objectives for phase contrast
- even different sets of objectives for different phase contrast techniques (positive, anoptral, amplitude, Zernike)
- a set of objectives for water immersion work, for example good and inexpensive Lomo objectives
- a set of objectives that all operate with oil immersion, for example Leitz Wetzlar 10x Oil / 25x Oil / 40x Oil
- a complete set of apochromatic objectives for obtaining better color reproduction
- a set of "P / Pol" objectives for polarization
- a complete set of objectives with only high magnifications, for example for analysis of cell wall ornamentation (50x / 63x / 80x / 100x)
- a set for dark field microscopy (objectives with an iris diaphragm inside)

Thanks to this, having only one microscope, we can use it for many different purposes without having to screw in and unscrew all objectives manually one by one every time.

Interestingly, regardless of the country (!) users often use English terms when referring to an objective nosepiece. The most common are:
- revolver
- objective nosepiece
- objective turret
- objective carousell
