CERTAIN, however according to my best knowledge the description should not be incorrect.

This is an element of the microscope head.
- based on the color I believe that this is a part manufactured by Nikon (from experience)
- based on the spacing of the screw holes I believe that this is the element to which a binocular tube (so-called "binocular") is attached
- it is NOT the actual bottom part of the microscope head housing, as in Nikon microscopes this is usually made of a metal casting (from experience)

If you are looking for this element because you need it to replace the one you have and which is, for example, damaged - then based on detailed photographs with a centimeter scale you will certainly recognize whether this is the part you need.

Basic parameters and technical data:
Element: microscope objective nosepiece
Manufacturer: Nikon
Manufacturer catalog part number: MBP71316
Manufacturer catalog designation: C-N6
Number of objective positions: 6
Thread: M25
Mounting method: dovetail

The nosepiece is mounted using a dovetail connection. This allows users who have more than one nosepiece to quickly exchange complete sets of objectives without removing them individually.
This makes it possible, for example, to keep a full set of low-magnification objectives on one nosepiece and a full set of high-magnification objectives on another, and quickly switch between them depending on current needs.

Description of this part for the microscope.

mechanical design.

This is the spherical rear reflector mounted inside the fluorescence illuminator behind the lamp. Its function is to collect and reflect the light that is emitted backwards and would otherwise be lost, directing it towards the collimating lens.

This particular reflector was removed from a fluorescence illuminator used on a Nikon Optiphot microscope. Hg 100W / HBO 100W illuminators of this type, or mechanically identical versions using the same rear reflector, were fitted to, among others:
- Nikon Optiphot
- Nikon Labophot
- Nikon Microphot

Therefore, the reflector presented here is also compatible with these microscopes. However, it should primarily be regarded as a replacement part for the fluorescence illuminator rather than for a specific microscope model.

When may the rear reflector need to be replaced?
- High-pressure fluorescence lamps used as the light source in these illuminators may explode, damaging the rear reflector and often the collimating lens as well.
- In addition, because the reflector is located immediately next to the light source, it is exposed to very high temperatures and is therefore susceptible to thermal damage.
- Another common issue is oxidation of the reflective surface over the course of decades. When this happens, the reflector loses its optical performance and the entire illuminator produces significantly less light.

Important: Nikon EPI fluorescence illuminators of that period were manufactured in several different lamp house versions. They are most commonly referred to simply as:
- Nikon Hg 100W
- Nikon HBO 100W
- Nikon HBO 100W HG Lamp House
- often the model is Nikon LH-M100CB-1

For confirmation of compatibility, the photo gallery includes precise dimensions of this component. The last photograph also shows the complete illuminator from which this reflector was removed, allowing compatibility to be verified with confidence.

lamp house.

This is the illumination collector lens combined with a heat absorbing filter that absorbs the heat generated by the light source (mercury arc lamp).

This particular collector lens and heat absorbing filter assembly was installed in a fluorescence illuminator used on a Nikon Optiphot microscope. Hg 100W / HBO 100W illuminators, or similar models with the same mechanical design and identical optics, were used in, among others, the following microscopes:
- Nikon Optiphot
- Nikon Labophot
- Nikon Microphot

Therefore, the optical module offered here is also compatible with these microscopes. First and foremost, it is a replacement part for repairing the illuminator rather than a specific microscope.

When may it become necessary to replace the heat absorbing filter or the collector lens that collimates the light beam?
- the high-pressure mercury arc lamps used as the light source in these illuminators may explode, damaging the rear reflector and often also the collimator lens.
- in addition, the collector lens located immediately next to the light source is particularly susceptible to damage due to prolonged exposure to high temperatures.
- another very common failure is that the filter simply cracks because of mechanical damage (although it is mounted without mechanical stress - it is intentionally fitted with slight clearance).

Important: Nikon EPI fluorescence illuminators from that period were manufactured with several different lamp house designs. They are most commonly referred to simply as:
- Nikon Hg 100W

illuminator housing.

This is the finned radiator mounted on the top of the fluorescence illuminator housing.

This particular finned radiator was originally installed in a fluorescence illuminator fitted to a Nikon Optiphot microscope. Hg 100W / HBO 100W fluorescence illuminators, as well as similar versions with the same mechanical design using the same passive finned radiator, were used in, among others, the following microscopes:
- Nikon Optiphot
- Nikon Labophot
- Nikon Microphot

Therefore, this cooling component is also compatible with these microscopes. Above all, it is a replacement part for repairing the fluorescence illuminator rather than a specific microscope.

The relatively fragile fins of this radiator are susceptible to mechanical damage (please note the small chipped area clearly shown in the video). In a fluorescence illuminator using a 100 W high-pressure mercury burner, efficient passive cooling is extremely important.

Important: Nikon EPI fluorescence illuminators from that period were manufactured with several different lamp house designs. They are most commonly referred to simply as:
- Nikon Hg 100W
- Nikon HBO 100W
- Nikon HBO 100W HG Lamp House
- often the model is Nikon LH-M100CB-1

For verification, the photo gallery includes the exact dimensions of this component. The last photograph also shows the complete fluorescence illuminator from which this finned radiator was removed, making it possible to confirm compatibility with complete confidence.

illuminator housing.

This particular mounting screw was part of a fluorescence illuminator installed on a Nikon Optiphot microscope. Hg 100W / HBO 100W fluorescence illuminators, as well as similar versions with the same mechanical design, were used in, among others, the following microscopes:
- Nikon Optiphot
- Nikon Labophot
- Nikon Microphot
- and the EPI fluorescence illuminators used with these microscopes

This mounting screw is frequently exposed to damage because it protrudes beyond the outline of the illuminator housing. As a result, it is often bent or even broken, especially during transport.

Replacing the microscope head mounting screw in Nikon Eclipse microscopes may be necessary, among other reasons, when:
- this screw is missing from the microscope, which is common in used microscopes
- the screw in the microscope is bent or broken, which is common when the microscope has not been properly secured for transport
- the screw in the microscope is in poor condition, e.g. damaged because someone tried to force it loose with pliers

for inverted and upright biological microscopes, made in Japan.

Basic objective parameters:
Manufacturer: Nikon, Japan
Model: Ph3 40 DL 0.55 LWD 160/0-2
Magnification: 40x
Numerical aperture (N.A.): 0.55
Optical correction: achromat
Phase contrast: Ph3 DL - Ph3 indicates the size of the phase ring (requires a matching Ph3 annulus in the condenser), DL (Dark Low) means dark, i.e. positive phase contrast - the object appears darker than the background
Working distance (WD): ~2.1 - 2.5 mm - LWD (Long Working Distance)
Correction collar: compensates for cover glass or vessel bottom thickness in the range 0 - 2.0 mm
Cover glass: the objective can be used without a cover glass, with a standard cover glass approx. 0.17 mm thick, and also with specimens observed through the bottom of a Petri dish up to 2.0 mm thick
Immersion: no (dry objective)
Tube length: 160 mm
Parfocal length: 45 mm
Thread: RMS
Optics: CF (Nikon CF-160) - requires no compensating eyepiece and allows photography by direct projection

This objective is suitable for:
- inverted microscopes - observation through the bottom of a Petri dish or cell culture flask
- upright biological microscopes - observation of specimens with or without a cover glass

Phase contrast work requires a compatible phase contrast condenser or a slider with a phase contrast annulus.

Commonly used, inexpensive cover glasses are 0.17 mm thick mainly in theory. Even the standard for class #1.5 allows a range of 0.16 - 0.19 mm, and in cheap Chinese cover glasses you will find in practice pieces from approx. 0.13 to 0.25 mm, often not matching the thickness stated on the box. Only #1.5H (high precision) cover glasses have a guaranteed thickness of 0.170 mm with a tolerance of +/- 0.005 mm. Variation in cover glass thickness clearly degrades image contrast and resolution (spherical aberration). The correction collar fitted to the objective offered here lets you adjust the optics to the combined thickness of the cover glass and the medium layer beneath it. This compensates for most of the variation found in practice.

In addition, the correction collar of this objective can be set to "0" for work without a cover glass, or to large values (up to 2.0 mm) to adapt the optics to observation through a microscope slide (0.8 - 1.2 mm), a glass Petri dish (usually 1.5 - 2.0 mm - thicker dishes are outside the collar range) or a plastic Petri dish (usually approx. 1 mm, in the range 0.8 - 1.2 mm).

This objective fits practically any microscope from any manufacturer, provided it has an RMS thread and uses objectives for 160 mm tube length with a parfocal length of 33, 37 or 45 mm. Some example microscopes are listed in the "compatibility" section, but the list is not complete.

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.

Each prism sits in its matching cradle (holder) made of cast metal. The manufacturer calls this holder a "prism seat". Offered here is the holder (seat) for the left inclining prism.

Replacing this inclining prism holder in the stereo head of the Nikon SMZ-10 microscope can help when the metal cradle holding the prism is broken. The cradle is made of a relatively brittle alloy and such damage is unfortunately not uncommon.

Such a broken seat, or a prism fitted without its seat - makes it impossible to set the correct collimation of the image and can lead to damage of the prism.

This round dovetail has a diameter of 60 mm.
The mount has two openings - one for each optical path. There is no optics in the openings - they are simply "empty holes" and this is their factory condition. It is true that in some stereo microscope heads the secondary objectives sit in the dovetail itself (for example in the PZO MST-130 microscope) - but in the Nikon SMZ-10 microscopes they sit on a separate element located deeper inside the head.

a modular photo output. Inside the fixed part of the trinocular, which is integrated with the head housing, sits a tube into which a photo eyepiece can be inserted. The manufacturer calls this element a "photographic lens holder".

Since the inner diameter of this tube is 23.2 mm, it takes the Nikon CF PL2.5X, Nikon PLI 5 and other photo eyepieces with this standard mounting diameter.

Inside this tube there is a helicoid mechanism for adjusting parfocality, so the sharpness of the image on the sensor of a camera can be tuned precisely.

Description of this part for the microscope.

version has a photo output in the form of a tube that takes a photo eyepiece (https://www.microscopeparts.eu/part/99891).

At the back of the head there is a switch that selects whether the image from the right or from the left optical path is sent to the trinocular output. On the outside this is done by a short knob. It shifts the set of mirrors sitting inside the head. This complete module is what is offered here.

This is an element exposed to many kinds of damage:
- the knob can get lost after unscrewing
- the knob can break off
- the mirrors can come loose from the metal frame they are glued to, and then they crack or chip easily
- the reflective surface of the mirrors can oxidise

In that case the best solution is to replace the whole module and in this way regain the ability to take photos with the stereo microscope.

Please note: this is a "CF" projection photo eyepiece, meaning "Chrome Free" (chromatic aberration free). The eyepiece itself carries no chromatic correction - for correct results it has to sit in the microscope objective. In the case of Nikon, those are the CF (CFN) and CFI objectives.

The standard 23.2 mm mounting diameter allows it to be used in the projection tubes of many microscopes from various manufacturers - both biological and stereo ones.

It has to be said that this is a very universal projection eyepiece. In the "compatibility" section I list only a small part of the microscopes this photo eyepiece can be used with.

From the experience of people I know, only testing a projection eyepiece yourself on a specific microscope setup gives you certainty about how it will behave.

With every configuration - different objectives, a different tube length, a different photo adapter, camera, DSLR, sensor size - the user will get a different result.

This applies to tests both on microscopes with finite tube length optics (for example the Nikon Labophot with 160 mm optics) and infinity optics (for example the Nikon Eclipse E600 infinity), and both on older stereo microscopes (for example the Nikon SMZ-10) and somewhat newer ones such as the Nikon SMZ-1500.

Please note: PLI is a series of projection eyepieces assigned to the CFI60 system (optics corrected for infinity / "I" as in "infinity"). I have, however, personally seen eyepieces from this series used on microscopes with optics corrected for a finite tube length (160 mm, to be precise).

This eyepiece contains no chromatic correction lenses, so that correction has to be built into the objective (in the case of Nikon objectives these are the CF / CFN / CFI series).

The standard 23.2 mm mounting diameter allows it to be used in the projection tubes of many microscopes from various manufacturers - both biological and stereo ones. It therefore has to be regarded as a very universal projection eyepiece. In the "compatibility" section I list only a small part of the microscopes this photo eyepiece can be used with.
