based on the N-117M / DN-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)

- 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 screw fits your microscope is to compare the appearance of your microscope with the microscope from which this screw was removed (https://www.microscopeparts.eu/microscope/optical-n-117m-388).

The N-117M version 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 head mounting screw is the same in both cases.

Replacing the head mounting screw may be necessary, for example, when:
- the screw is missing from the microscope, which is common with used microscopes
- the screw in the microscope is bent or broken, which often happens when the microscope is not properly secured for transport
- the screw in the microscope is in poor condition, e.g. damaged because someone tried to force it out with pliers

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.

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.

this mounting bracket is located at the end of the microscope stand arm. The microscope head is mounted to this bracket from above, while the objective nosepiece is located below it.

The entire mounting module for both the microscope head and the objective nosepiece consists of the following elements:
- the mounting socket into which the microscope head dovetail is inserted
- the clamping screw that secures the microscope head in this connection
- the Telan lens screwed into this mounting socket, which also holds the objective nosepiece

Here I am presenting the first of these elements - the microscope head connection (mounting socket / bracket).

Microscopes based on the N-117M model have an objective nosepiece tilted inward, and in my opinion this is why a Telan lens is required even though this is a microscope using optics corrected for a 160 mm tube length.

Other names are sometimes used for the Telan lens installed in the microscope, for example:
- nosepiece lens
- intermediate lens
- tube lens (although this is an incorrect term, because a really "Tube lens" has a different function)

When might this microscope part need to be replaced?
- if the microscope has a condenser holder in which the clamping screw is missing, bent, or broken off with a fragment remaining in the thread. This is a common fault
- if the clamp is missing from the inside of the condenser holder - this is a common problem because the clamp can be pulled out
- if the metal ring of the condenser holder has been bent as a result of an impact; in this case, the condenser simply cannot be inserted into the holder

This microscope base contains:
- a socket for connecting the power cord
- an ON / OFF switch
- a knob for adjusting the light intensity (brighter-darker)
- the necessary internal electronics
- an LED light source
- IMPORTANT - as can be seen in the photos, there is no light collector in the base

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, from "Digital") - however, the base is shared and fits both of these models.

Some older versions of microscopes based on the N-117M design have halogen illumination (rather than LED, as in the base presented here) - but the shape and the way the base is attached to the microscope arm are the same. A base with halogen illumination and a base with LED illumination can therefore be used interchangeably as a way of upgrading the microscope.

When might it be necessary to replace the microscope base?
- if the microscope base is of very poor quality (it may sometimes have been broken during transport)
- if you want to replace a base with halogen illumination with one with LED illumination
- if something inside the existing base has been damaged: the electronics, switch, or brightness adjustment knob

Description of this part for the microscope.

10 160/-
Numerical aperture N.A.: 0.10
Cover glass: not required
Thread: RMS
Tube length: 160 mm
Parfocal distance: 45 mm (so-called long objective)
Immersion: no (dry objective)

This objective can be used:
- on biological transmitted light microscopes
- on inverted microscopes
- on microscopes with a reflected light illuminator
- for macro photography, connected directly to a camera

This is the so-called black series of objectives, named after the black plastic objective barrel. They were used mainly in the Will Wetzlar microscopes of the V300 series, for example in the Wilozyt V365 model. This was the period when manufacturers were experimenting with a new look for microscope parts, and exactly the same black series appeared, for example, in the Leitz Wetzlar HM-LUX-3 microscopes.

It is worth noting that the Will Wetzlar microscopes of the V100 and V200 series were usually fitted with objectives of 37 mm parfocal distance - but newer objectives with a parfocal distance of 45 mm, such as those of the black series, can be used in them without any problems whatsoever.

The companies Eschenbach, Kremp Wetzlar, CBS Beck Kassel, Kosmos Stuttgart and Hund Wetzlar also used objectives made by Will Wetzlar, although these often carried their own company name. It can therefore be said with a high degree of confidence that this objective will also fit the microscopes of those companies.

This objective fits practically any microscope of any make, provided it has an RMS thread and accepts objectives with TL=160 mm and parfocal distances of 33 / 37 and 45 mm. A few examples of such microscopes are listed in the "kompatybilność" section, but that list is not exhaustive.

This was the period when manufacturers were experimenting with a new look for microscope parts, and exactly the same black series appeared, for example, in the Leitz Wetzlar HM-LUX-3 microscopes.

It is worth noting that the Will Wetzlar microscopes of the V100 and V200 series were usually fitted with objectives of 37 mm parfocal distance - but newer objectives with a parfocal distance of 45 mm, such as those of the black series, can be used in them without any problems whatsoever.

The companies Eschenbach, Kremp Wetzlar, CBS Beck Kassel, Kosmos Stuttgart and Hund Wetzlar also used objectives made by Will Wetzlar, although these often carried their own company name. It can therefore be said with a high degree of confidence that this objective will also fit the microscopes of those companies.

This objective fits practically any microscope of any make, provided it has an RMS thread and accepts objectives with TL=160 mm and parfocal distances of 33 / 37 and 45 mm. A few examples of such microscopes are listed in the "kompatybilność" section, but that list is not exhaustive.

Cover glass: yes, 0.17 mm
Thread: RMS
Tube length: 160 mm
Parfocal length: 45 mm (so-called long barrel objective)
Immersion: yes, oil

This is the so-called "black series" of objectives, named after the black plastic housing of the objective. They were used mainly in Leitz Wetzlar HM-LUX-3 microscopes (and in the model signed Leica HM-LUX 3). This was the period when manufacturers were experimenting with a new look for microscope parts, and exactly the same kind of "black series" could also be found in Will Wetzlar V300 / V355 / V365 or Nikon Alphaphot YS2 microscopes.

This objective fits practically any microscope from any manufacturer, provided it has an RMS thread and accepts objectives with a tube length of 160 mm and a parfocal length of 33 / 37 or 45 mm. A few such microscopes are listed as examples in the "compatibility" section, but this is not a complete list.

Tube length: 160 mm
Parfocal length: 45 mm (so-called long barrel objective)
Immersion: no (dry objective)

This is the so-called "black series" of objectives, named after the black plastic housing of the objective. They were used mainly in Leitz Wetzlar HM-LUX-3 microscopes (and in the model signed Leica HM-LUX 3). This was the period when manufacturers were experimenting with a new look for microscope parts, and exactly the same kind of "black series" could also be found in Will Wetzlar V300 / V355 / V365 or Nikon Alphaphot YS2 microscopes.

From 1990 onwards, the logo (and the name) "Leica" began to appear on microscopes that had until then been signed "Leitz". This was also visible on the HM-LUX 3 microscope - and this microscope can be found both with the "Leitz" logo and with "Leica". The same 10x objective that I present here with the name "Leitz Wetzlar" and manufacturer number 519754 also exists with the "Leica" marking - and NOTE - it carries exactly the same number, that is "519754".

This objective fits practically any microscope from any manufacturer, provided it has an RMS thread and accepts objectives with a tube length of 160 mm and a parfocal length of 33 / 37 or 45 mm. A few such microscopes are listed as examples in the "compatibility" section, but this is not a complete list.

of view number: 12
Mounting diameter: 23.2 mm
Designation: PK = plan compensating - recommended for work with planachromatic objectives, but they also work without any trouble with achromats or apochromats

Because of their very high quality they are often used on microscopes from other manufacturers as well, especially when Carl Zeiss Jena Planachromat objectives are mounted in them. The "compatibility" section lists a long series of microscopes these eyepieces fit - but that list is definitely not complete.

Important: these eyepieces work both on microscopes with a finite tube length (160 mm, for example) and on microscopes with infinity optics. That means you can use them on the Carl Zeiss Jena Amplival microscope just as well as on the Carl Zeiss Jena NU-2 microscope.

A note - eyepieces with such a strong magnification are in my opinion better suited to a quick look than to permanent work. I write "in my opinion" on purpose, because this comes from using them and not from the manufacturer's description.
A 16x eyepiece magnification should be treated as a zoom that brings out no additional detail (the resolution is not increased). This matters for example with heads that have their own extra magnification (such as Carl Zeiss Jena heads with a built-in 1.5x or 1.6x factor) - working with a 100x oil immersion objective you then theoretically get 100*1.5*16 = 2400x, while physics does not allow light from the visible range to be usefully magnified for the human eye beyond roughly 1250x - so this is what is called empty magnification.

Cover glass: yes, 0.17 mm thick
Thread: RMS
Tube length: 160 mm
Parfocal length: 45 mm (long barrel objective)
Immersion: yes, oil
Operating mode: objectives marked "E." are already CF objectives (CFN to be precise) and need no additional correction

This objective needs no additional correction from a tube lens or from the eyepieces. That makes it possible to fit it to microscopes of other makes, and in photomicrography it works in direct projection mode (it throws the image straight onto the camera sensor, with no relay optics needed).

This is the so-called black series of objectives, named after the black plastic barrel. They were used mainly in the Nikon Alphaphot YS2 microscope. That was the period when manufacturers were experimenting with a new look for microscope parts, and exactly the same black series appeared for instance in the Leitz / Leica HM-LUX 3 microscope or in the Will Wetzlar V300 / V355 / V365 microscopes.

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.

- clamping screw that holds the microscope in the collar
- rack along which the microscope moves up and down inside the collar (also available separately https://www.microscopeparts.eu/part/91079)
- knobs that produce this movement, that is the focusing knobs (also available separately https://www.microscopeparts.eu/part/91063)
- internal shaft with a pinion that converts the rotary movement into vertical movement along the rack (also available separately https://www.microscopeparts.eu/part/91064)
- mounting block with a hole for fitting it onto the stand pillar
- inside the hole there is a split clamping sleeve with a screw driven in from the outside, locking the whole holder at the required height (also available separately)

Basic parameters of this holder:
Inner diameter of the collar: 50 mm (yes - 50 mm is not a mistake, this diameter is not commonly used on the market)
Diameter of the hole for the stand pillar: 24 mm (yes - 24 mm. This is not a measuring error)

Since these are unusual dimensions and you may suspect a measuring error, the gallery contains photos taken with a caliper as well as a photo of the stand pillar. The pillar is not part of this offer, but I do have it - if you need it, that is no problem :)

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

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.

profile with a C-mount thread. The filter measures approx. 15x15 mm (+/- 1 mm).

This threaded aluminium profile is a part of the housing of the Imaging Source DFK41AU02 USB microscope camera.

Since this is a typical mass-produced item from a Chinese factory, it is quite possible that, once unglued from the housing, this filter will fit many other cameras as well.

In the microscope camera this filter sits inside a short tube with a C-mount thread and, apart from blocking infrared light, it also protects the sensor against dirt. The glass cracks very often, so it has to be replaced. In addition, users sometimes carry out DIY modifications and remove the IR-cut filters from their cameras. The glass is frequently damaged during that operation. In such a case this very filter, which I offer here, can help to bring the camera back to its original condition.

Once unglued, the filter can be used for microscopes, for macro photography in the broad sense, for photomicrography or for your own DIY projects.

microscope cameras in the so-called cube housings are built from several electronic modules connected to each other. These are usually universal modules from Chinese factories, which OEM manufacturers then use in their own products.

Here I offer exactly such a module, with the CCD sensor on one side of the board and the connector for the next module on the other side.
