The M-9 microscope was manufactured before World War II at the Soviet Progress (later Lomo) factory. It is often believed to be a direct descendant of the small MBI and MBR series microscopes, but this is not true, as the MBR-3 and MBI-1 are copies of the German L-Stativ.

This cap covers and holds the spring, which is part of the fine (micro) advance mechanism.

The plate also contains the serial number, which begins with the year of manufacture (here, 73).

The markings placed immediately after the model name (here Y 4.2) mean:

Y 4.2: means a microscope or a microscope part adapted for operation in rooms with moderate humidity and within a temperature range of 10°C - 35°C.
T 4.2: means a microscope or a microscope part adapted for operation in rooms with extremely dry air or with high humidity in a tropical climate and within a temperature range of 10°C - 45°C.

and focusing is achieved by raising or lowering the microscope stage. This is the opposite of how it works, for example, in the Lomo Biolam model, where the arm moves up and down.

Along this rack gear offered here, the entire assembly of the microscope stage holder and the condenser is moved. This assembly is driven by a gear wheel mounted on a shaft located between the coarse focus knobs.

This is an original brass rack gear, not a plastic 3D print. The set includes two mounting screws (the upper and lower ones differ from each other).

Note - Lomo MBI-1, MBR-3 or Lomo Biolam microscopes use a DIFFERENT rack gear for the condenser movement mechanism.

The head of this microscope contains two such holders - one for each eyepiece tube. Both are identical, which means there is no difference between the right and left side.

On a mechanical microscope stage there are two such clamps, between which a microscope slide with a specimen is placed. These clamps - right and left are not identical. Here I present and offer the left clamp, which does not have a spring.

Note - different stage models use different clamps. In the photo gallery there are detailed photos of this element along with dimensions. In the last photo, the stage to which this clamp fits is shown. Additionally, an arrow indicates where this element is located, so it is clear which part of the microscope stage is being referred to.

These are the exact components marked with numbers 3 and 5 in the instruction manual sketch.

117M models.

The N-117M / DN-117M is a reasonably good laboratory microscope manufactured in a 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 United Kingdom)
- 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 United Kingdom)
- Apex N-117M (mainly in the United Kingdom)
- 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 their microscopes their own names, just as Delta Optical does in Poland. The best way to check whether this rack fits your microscope is to compare the appearance of your microscope with the microscope from which this rack was removed (https://www.microscopeparts.eu/microscope/optical-n-117m-388).

The N-117M model has a binocular or trinocular microscope head, while the DN-117M model has a built-in digital USB camera (hence the "D" at the beginning of the name, standing for "Digital") - however, the entire body, and therefore also the condenser height adjustment rack, is the same in both models.

Since the rack of the condenser height adjustment mechanism in this microscope model is made of plastic, it is a component that is very frequently damaged.

mechanical microscope stage, allowing precise movement of the specimen in both the X and Y axes of the stage plane. The manipulator consists of two coaxial knobs, two independent drive shafts and the fixing elements that attach it to the stage mechanism.

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 microscope body is identical, so the stage control handle is also the same in both models.

On the second-hand market and in service documentation one encounters many names referring to this assembly. The most commonly used terms include, among others:
- stage manipulator
- XY stage manipulator
- mechanical stage drive
- stage control knobs
- specimen mover
- coaxial stage drive
- stage drive assembly
- mechanical stage control
- manual XY stage drive
- stage actuator mechanism

Such manipulators very often suffer mechanical damage during transport of the microscope. Because they protrude beyond the outline of the stand, it is precisely they that absorb the impact energy first - in the event of a fall or improper packaging of the instrument.

Damage to the manipulator does not make further work with the microscope impossible. The specimen can be moved by hand, or a simple specimen holder without an XY movement mechanism can be fitted. Such a solution works well at low magnifications; however, when working with objectives of magnifications greater than 40x (e.g. 60x, 63x, 80x or 100x), precise manual movement of the specimen becomes very difficult. At total magnifications exceeding about 400x, even a slight movement of the hand shifts the image by a considerable distance within the field of view. The mechanical manipulator enables very smooth, controlled and repeatable movement of the specimen in both axes, which is particularly important during observation with oil immersion and when producing photographic documentation.

The photographs in the gallery show the exact dimensions of the complete manipulator. The last photograph presents the entire microscope stage together with an arrow indicating the mounting location of this element, which makes it possible to identify the offered part unambiguously.

mm
Diameter of the knob on the focusing holder side: 28 mm
Mounting on the pinion shaft: the knob has a threaded hole into which the pinion shaft is screwed, as the shaft is threaded at both ends. Once screwed in, the shaft is additionally secured with two screws
Threaded hole diameter: 5 mm

It is very likely that Nissho Optical (NSK for short) uses identical knobs across its whole range of stereo microscopes, or more precisely: in the head holders of those microscopes. I give the dimensions of this knob in the parameter block so that you can check compatibility if you are looking for a knob for a model other than the "209".

The focusing holder of a stereo microscope contains two such knobs. Both are identical, so there is no difference between the right-hand and the left-hand knob. I offer each of these knobs separately, as a single item.

The last photo shows the coarse focusing holder of the Nissho Optical 209 stereo microscope, with an arrow pointing out which knobs are meant and where they are located.

two parts:
- aluminium clamping sleeve, split along its whole length, which is inserted into the hole in the mounting block of the head holder
- screw with a three-lobe knob, driven in from the outside

This clamping sleeve comes from the head holder for the Nissho Optical 209 microscope (the complete holder is available here https://www.microscopeparts.eu/part/91077).

It is very likely that Nissho Optical (NSK for short) uses identical sleeves across the whole series of stereo microscope head holders it manufactured.

Without this part the holder with the stereo microscope head cannot be clamped precisely at a given height on the stand.

The last photo in the gallery shows the measurement of the pillar that the stereo microscope head holder is fitted onto, and in which this clamping sleeve belongs. The pillar has an unusual diameter - 24 mm - and this matters to anyone who would like to use the sleeve in other microscopes.
