- 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 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.

I've also used the Olympus BHM microscope with Carl Zeiss Jena M25 thread objectives (Jenaval microscope objectives), and they fit and work very well :-)

I'm almost certain (but I haven't checked) that this turret fits the Olympus BH model (but not the BH-2), which has a turret for RMS objectives by default. However, it can be swapped out and work with an M25 objective :)

This turret mounts with a dovetail joint, allowing you to quickly swap out entire sets of objectives without having to unscrew them individually if you have more than one turret.
This allows you to have a complete set of low-power objectives on one turret and a complete set of high-power objectives on the other, quickly swapping them as needed.

Description of this part for the microscope.

For example, you can have a single Vickers Patholux microscope and separate revolvers already fitted with such objective sets:
- low-magnification objectives for observing macro objects with EPI illumination, without a cover slip (e.g., 2.5x / 3.2x / 5x / 8x)
- objectives for phase contrast; for different phase contrasts: positive, anoptral, variable, amplitude, Zernike
- DIC objectives
- water immersion objectives (e.g., by Lomo)
- all oil immersion objectives (e.g., Leitz 10x Oil, 25x Oil, 40x Oil, and 100x Oil)
- apochromatic objectives for better colors
- polarization objectives
- high-magnification objectives, e.g., for analyzing cell wall ornamentation (50x / 63x / 80x / 100x)
- dark-field objectives (objectives with an iris diaphragm inside)

This way, having only one microscope, you can use it for various purposes without manually screwing and unscrewing all objectives piece by piece every time.

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

nosepiece.

This holder is compatible with the following polarizing microscopes:
- Lomo Polam L-211
- Lomo Polam L-213
- Lomo Polam LMPR

The microscope models listed above are equipped with a removable 5-position objective nosepiece that can be removed and replaced with this single objective holder. A single-objective configuration has long been a standard solution in polarizing microscopy, and many users still prefer it today.

Simpler models, such as the Lomo Polam C-111 (Latin transcription S-111) and P-111 (Latin transcription R-111), do not have a removable objective nosepiece. Therefore, this holder is not compatible with those models.

Important:
The objective is not screwed directly into this holder. This holder does not have an RMS thread. It accepts objectives that have already been mounted in dedicated centering adapters. These adapters provide the precise objective centering required for polarizing microscopy.

The manufacturer illustrates this holder in Figure 4 of the instruction manual (item 47) and refers to it as щипцовое устройство (shchipcovoe ustrojstvo - pincer device).

Several names are commonly used for this component in documentation and among microscope users, including:
- single objective holder
- single objective mount
- objective holder
- objective clamp
- objective carrier
- pincer holder
- single objective nosepiece
- objective socket
- the English term "single objective microscope nosepiece" is very commonly used, even though it is technically associated with a revolving nosepiece

If you need additional comparison photographs, this database also contains:
- the 5-position objective nosepiece for this microscope model (part number 00798)
- the centering adapter for a single RMS objective (supplied together with the objective as part number 00772)

positions: 6
- Thread: M25
- Mounting method: screw-mounted to the intermediate bracket (nosepiece holder), between the nosepiece and the microscope body

The complete objective nosepiece module for Carl Zeiss Jena Jenalumar or Jenaval microscopes consists of:
- the objective revolver (also called the objective nosepiece, nosepiece disc or objective turret)
- the intermediate mounting bracket (nosepiece holder).

In both microscope models, the Carl Zeiss Jena Jenalumar and the Carl Zeiss Jena Jenaval, the first component - the objective revolver - is identical and interchangeable between the two models. Only the intermediate mounting bracket differs, as it attaches the revolver to the microscope arm. In other words, the nosepiece holder used in the Carl Zeiss Jena Jenalumar microscope is different from the one used in the Carl Zeiss Jena Jenaval microscope, but both holders have exactly the same objective revolver attached to them.

This offer includes only the objective turret, without the mounting bracket.

The gallery contains photographs of a Carl Zeiss Jena Jenalumar microscope arm, with the objective nosepiece indicated by an arrow to clearly show its location. It also includes photographs of the complete module consisting of the objective revolver and its holder for the Jenalumar microscope, making it clear how these two components are connected.

This database also contains, under item number 99388, the complete objective nosepiece module with its holder for the Carl Zeiss Jena Jenaval microscope.

117M microscope is a fairly good laboratory microscope manufactured at the Chinese NYO factory and sold worldwide under various names. These microscopes are known and sold, among others, as:
- Delta Optical Genetic Pro (mainly in Poland)
- AmScope B340 / T340 (mainly in the USA and the rest of the world through Amazon)
- Labtron LEM-C10 / C11 / C12 (mainly in the UK)
- Sigeta MB-207 (mainly in Ukraine)
- Boeco Germany BM-117 (mainly in Germany)
- BestScope BS-2020 (mainly in the USA, shipped worldwide)
- Brunel N117M (mainly in the UK)
- Apex N-117M (mainly in the UK)
- Surgifield SM-DN-117M (mainly in Nigeria and West Africa)
- Eurotech DN-117M (mainly in Peru)
- Biocare DN-117M (mainly in Peru)
- Viresa N-117M (mainly in Mexico)
- Eurolab DN-117M
- Nexcope N-117M
- Novel N-117M

This is certainly not a complete list - many sellers give the microscopes they sell their own names (just like Delta Optical in Poland). The best way to check whether this nosepiece fits your microscope is to compare the appearance of your microscope with the microscope from which this microscope part was removed (https://www.microscopeparts.eu/microscope/optical-n-117m-388).

The N-117M model has a binocular or trinocular head, while the DN-117M model has a built-in digital USB camera (hence the "D" at the beginning of the name, for "Digital") - but the entire microscope body, and therefore the nosepiece as well, is identical in both models.

written: 450905). It also fits the following variants:
- Zeiss Axiolab drb KT, which carries the same number 45 09 05 (450905)
- Zeiss Axiolab E re, 45 09 07 (450907)
- Zeiss Axiolab A, (reflected light), 45 09 09 (450909)

The Zeiss Axiolab Pol (P/N 45 09 10) comes from the factory with a pol nosepiece, meaning each objective position can be centred. Mechanically, the nosepiece offered here can be fitted to a Zeiss Axiolab Pol - but centring the objectives will not be possible. It is still a workable stopgap if an Axiolab Pol urgently needs to run again, especially when no pol objectives are going to be used.

Please note: the visually very (!) similar microscopes:
- Zeiss Standard 20
- Zeiss Standard 25 ICS
- Zeiss Axiostar
have DIFFERENT (!) nosepieces, and the one from the Zeiss Axiolab will NOT (!) fit them.

This nosepiece is fastened to the microscope arm with three screws (they are included in the set offered here), it is screwed onto the microscope arm from above, and the screws sit in the recess of the head mount.

The housing that forms one unit with this nosepiece has two slots for sliders. Two empty plastic sliders are included and can be seen in the gallery photos.

Several different names are in use for this part. They all mean the same thing, among them:
- revolving nosepiece
- objective turret
- objective nosepiece
- nosepiece turret
- objective changer

In the last gallery photo you will see a Zeiss Axiolab re with an arrow marking which part is meant and where it sits on the microscope. That makes it unambiguous to identify.

among others:
- Lomo Erudit (ЛОМО Эрудит)
- Lomo Biolam 70
- Lomo Micmed-1
- Lomo Biolam Д1 / Д2 / Д3 / Д11 / Д12 / Д13 (D series - portable)
- Lomo Biolam C1 / C2 / C3 / C11 / C12 / C13 (S series - for students)
- Lomo Biolam P1 / P2 / P3 / P4 / P5 / P6 / P7 / P11 / P12 / P13 / P14 / P15 / P16 / P17 (R series - working microscopes)
- the microscopes sold in Germany under the names Bresser Biolam and Bresser Erudit, including the newest ones with illumination integrated into the base
- and the same microscopes sold in the United Kingdom under the name Zenith Biolam

In addition, this nosepiece can be used in the older, black LOMO microscopes (although it will not look elegant):
- Lomo MBI-1 (ЛОМО МБИ-1)
- Lomo MBR-1 / MBR-3 (ЛОМО МБР-1 / МБР-3)
- Lomo MBB-1A (ЛОМО МББ-1A)

Why should every microscope user own more than one objective nosepiece?

LOMO microscopes - the older silver and black models as much as the newer grey and the newest white ones - have an interchangeable objective nosepiece. That is an excellent arrangement, because it lets you keep whole sets of objectives ready and swap them in seconds.

You can, for example, have separate nosepieces with the objectives already screwed in:
- a set of low-magnification objectives for macro observation with side illumination, without a cover glass (for example 2.5x / 3.2x / 5x / 8x)
- a set of phase contrast objectives (marked Ф or Ф-2)
- a set of objectives for work with water immersion (marked ВИ)
- a set of objectives that all work with oil immersion (marked МИ)
- a set of apochromatic objectives for better colours (marked АПО or АПОХР.)
- a set of objectives for polarisation (marked П)
- a set of objectives with high magnifications only, for example to analyse the ornamentation of the cell wall (50x / 63x / 80x / 100x)
- a set for dark field work (objectives with an iris diaphragm inside)
- a set of objectives for work without a cover glass, even at high magnifications (marked Д=0)
- a set of objectives for fluorescence (marked Л)

A single microscope can then serve several purposes, without screwing every objective in and out by hand each time.

Several different names are in use for this part. They all mean the same thing, among them:
- revolving nosepiece
- objective turret
- objective nosepiece
- nosepiece turret
- objective changer

In the last photo in the gallery you will see the LOMO Biolam R-1 microscope, with an arrow showing which part is meant and where it is located on the microscope. That makes it possible to identify it without any doubt.

A reminder: this nosepiece is partly painted grey. LOMO also made such nosepieces in black (for the older microscopes, for example MBI-1, MBP-3, MBB-1A - that is, before the Biolam era) and in white (for the newer Biolam models after the collapse of the USSR, and for the newest ones sold under the Bresser brand). They are all mechanically identical and compatible, so for example a black nosepiece from a Lomo MBB-1A or MBP-3 can be used on a Lomo Biolam and the other way round - grey or white nosepieces from new Lomo Biolam microscopes can be fitted to black Lomo MBB-1A microscopes and even to the oldest, hammered-silver MBI-1.

ЛОМО marked the series in Cyrillic letters, so the letter engraved on the microscope does not always mean what it seems to mean at first glance: Д stands for the Latin D, but the Russian C is read as S and the Russian P as R.

The same models in the notation used on Western markets:
- Lomo Biolam D-1 / D-2 / D-3
- Lomo Biolam S-1 / S-2 / S-3
- Lomo Biolam R-1 / R-2 / R-3 / R-4 / R-5 / R-6 / R-7
- Lomo Biolam D-11 / D-12 / D-13
- Lomo Biolam S-11 / S-12 / S-13
- Lomo Biolam R-11 / R-12 / R-13 / R-14 / R-15 / R-16 / R-17
