Description of this part for the microscope.

In practice, it works like a "single-objective nosepiece".

A M27 - RMS adapter is screwed into this adapter, allowing an objective with RMS thread to be mounted.

Note: MMU-3 is the model name written in the Latin alphabet. The original model name is written in Cyrillic and looks similar to "MMY-3".

The last images include scans from the instruction manual clearly showing which element this is.

The light source is inserted into this housing (the standard light source in this model is an 8V 20W bulb). The entire housing is covered with dense metal fins acting as a heat sink to dissipate heat. At the end of this housing there is a condenser lens collimating the light beam and a dovetail mount. This mount is used to attach the condenser to the next element of the illumination path, namely the holder with a slot for insertable sliders.

The model designation MMU-3 is written using the Latin alphabet. When written in Cyrillic, this designation looks like MMY-3, and people unfamiliar with the Cyrillic alphabet may therefore refer to this microscope model in that way.

Interestingly, the dovetail connection used here has a diameter of 41.5 mm, which is the standard mounting diameter for accessories (for example microscope heads and intermediate tubes) not only in Lomo microscopes, but also in Carl Zeiss Jena, Romanian IOR, Czechoslovak Meopta and many other microscopes. For this reason, this lamp housing is sometimes used as an EPI reflected light source in various Carl Zeiss Jena microscope modifications.

microscope stage. It is also possible to mount a specialized stage on the side rails - these rails are visible in the photographs and are located on both sides of this stand base.

is to switch the reflected-light operating mode between darkfield and brightfield observation.

This slider is inserted into a slot located in the Lomo MMU-3 microscope between the microscope body and the lamp housing.

This slider has two positions:
1. Darkfield stop (darkfield disc). When the slider is set to this position, the microscope can be used for reflected-light darkfield observations.
2. Frosted diffuser filter with an iris diaphragm. When the slider is set to this position, the microscope can be used for reflected-light brightfield observations.

Description of this part for the microscope.

This microscope part performs two essential functions:
- mounting the microscope body onto the stand column
- providing coarse focus (macro movement) along the permanently mounted rack

More precisely, this assembly consists of the following components:
- stand column clamp
- stand column locking screw
- dovetail guide on which the microscope body with the optics moves
- rack on which the microscope body with the optics moves

Please note:
- the original Cyrillic designation of this model is: ЛОМО ММУ-3
- for people using the Latin alphabet who know that the manufacturer is "Lomo", it visually appears as: Lomo MMY-3
- however, the original designation is pronounced: Lomo MMU-3

The last photograph in the gallery includes an arrow indicating exactly which microscope part is being offered and where it is installed inside the microscope, making it easy to identify this component unambiguously.

part is an intermediate tube located in the optical path between the reflected-light illuminator with its condenser and the microscope body. It performs two functions:
- on one side it is attached to the microscope body, and this side contains the slot into which the iris diaphragm slide is inserted
- on the opposite side there is a dovetail mount for the illuminator assembly

Please note:
- the original Cyrillic designation of this model is: ЛОМО ММУ-3
- for users of the Latin alphabet who know that the manufacturer is "Lomo", the designation looks like: Lomo MMY-3
- however, the original designation is read as: Lomo MMU-3

The last photograph shows this microscope part indicated with an arrow and its exact position inside the microscope, allowing it to be identified unambiguously.

220V - 240V
Output: 8V
Output power: 20W
Power plug: European flat plug
Potentiometer: yes, smooth brightness adjustment

Designed for:
- Lomo OI-21 illuminator
- Lomo OI-35 illuminator
- illuminator used with MBC-9 and MBC-10 stereo microscopes

Also compatible with older black Lomo microscopes:
- MBB-1
- MIN-8
- EPI reflected-light illuminators, including those used with the Lomo METAM and Lomo MMU-3
- and many others

Some older Lomo microscopes (for example, the MBC-1 and MBC-2 stereo microscopes) may use different connectors, but they use the same Lomo 8V 20W BA15d lamps.
