9904
Magnification: 10x
Correction: achromat
Numerical aperture: 0.22
Tube length: 160 mm
Focal length: 45 mm
Cover glass: indifferent
Immersion: no
Thread: RMS
Ph1: phase contrast

This specific unit was used in an inverted Zeiss ID 02 microscope, but I have also seen this objective model in Zeiss KF-2 ICS and Zeiss Axiostar microscopes.

Objectives with such low magnification (here 10x) can be used without a cover glass, with a cover glass, or for observation through thicker glass (e.g. through a Petri dish), therefore they can be used both in upright and inverted microscopes.

It can be used with any microscope from any manufacturer together with a compatible phase contrast condenser (or slider with phase rings). Of course the microscope must be compatible, i.e. support RMS objectives, TL=160 mm, FL=45 mm.

number: 46 07 01 - 9903
Magnification: 40x
Correction: achromatic
Numerical aperture N.A.: 0.65
Tube length: 160 mm
Focal length: 45 mm
Cover glass: yes, 0.17 mm
Immersion: no
Thread: RMS
Ph2: phase contrast

This particular specimen was used in a Zeiss KM microscope, but I have also seen this objective model in Zeiss KF-2 ICS and Zeiss Axiostar microscopes. It fits many microscope models from this manufacturer; some examples are listed in the "compatibility" section.

It can be used with any microscope from any manufacturer together with a suitable phase-contrast condenser (or a phase-ring slider). Of course, the microscope must be compatible, i.e. support RMS objectives, TL=160 mm and FL=45 mm.

Description of this part for the microscope.

Germany
Designation: Ph2 F40/0,65 160/0,17
Manufacturer catalogue number: 46 07 06
Magnification: 40x
Correction: Semi-planachromatic
Numerical aperture N.A.: 0.65
Tube length: 160 mm
Parfocal length: 45 mm
Cover glass: yes, 0.17 mm thick
Immersion: no (a so-called dry objective)
Thread: RMS
Phase contrast: yes, the objective has an internal phase ring matching the Ph2 position in the condenser
Specimen protection: yes, the objective has a spring-loaded mechanism that protects the slide from being crushed

The letter "F" at the beginning of the objective model name (F 40 / 0.65) means that this is a semi-planachromatic objective, i.e. flatter than an achromat but less flat than a planachromat. "F" does not mean that the objective is intended for work with fluorescence light.

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

P/N 45 09 05 (also 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 Pol, 45 09 10 (450910)

This is the plate that the transformer electronics are originally screwed to from the inside (if the microscope has them). What I offer here is the plate only - the bare cover - nothing more.

Many people treat the cover plate and the power supply as one single part. So when the power supply burns out, it is usually unscrewed together with the plate - and taken to the repair shop that way. If the power supply cannot be saved, it often never comes back... and unfortunately neither does the body cover.

In that case the options are:
- cut the cover yourself out of cardboard
- print the cover on a 3D printer
- or simply buy an original cover, like the one offered here.

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.

P/N 45 09 05 (also written as 450905). However, 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)
- Zeiss Axiolab Pol, 45 09 10 (450910)

The knob carries a collar with a 0-360 scale, which is an angular measure describing one full turn of the knob.

The knob is mounted on the shaft (the shaft inside the stand body that connects the knobs on the right and the left side of the microscope) with a small grub screw, which is included.

I was not able to confirm this, but in my opinion it is very likely that this knob also fits the following microscopes:
- Zeiss Standard 20
- Zeiss Standard 25 ICS
- Zeiss Axiostar
- Zeiss Axioskop 20
- Zeiss Axiovert 25

The Carl Zeiss Axiolab microscope has two such knobs. Both are identical, so there is no difference between the right and the left knob. I am offering each of these knobs separately (one at a time).

The last photo shows the stand of the Zeiss Axiolab microscope, with an arrow pointing at the knobs in question.

which sits on the outside of the microscope housing
- the potentiometer
- the 3-wire cable with a flat plug

Purpose: brightness control of the 6V 20W-25W and 30W halogen bulb. This potentiometer has to work together with the electronics of the transformer built into the microscope body.

This potentiometer was removed from a Zeiss Axiolab re microscope, P/N 45 09 05 (also written as 450905). However, 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, 45 09 09 (450909)
- Zeiss Axiolab Pol, 45 09 10 (450910)

I was not able to confirm this, but in my opinion it is very likely that the potentiometer from the Zeiss Axiolab microscope also fits the following microscopes:
- Zeiss Standard 20
- Zeiss Standard 25 ICS
- Zeiss Axiostar
- Zeiss Axioskop 20
- Zeiss Axiovert 25

The part offered here can be a remedy for the following problems with a Zeiss microscope:
- if the illumination intensity control in the microscope has stopped working completely (but be careful, the cause may also lie on the side of the electronics)
- if the bulb flickers while you adjust the brightness
- if, for example, due to mechanical damage the knob has broken off your potentiometer

The last photo shows the stand of the Zeiss Axiolab re microscope, with an arrow pointing at the place on the microscope housing where the knob controlling this potentiometer is located.

fixed to the casting number 6527 with two hex socket screws. This is the casting of the stage carrier, because in the Axiolab focusing is done by lowering and raising the condenser and stage unit. The screws that hold the rack to this casting are included in the set offered here.

This toothed rack was removed from a Zeiss Axiolab re microscope, P/N 45 09 05 (also written as 450905). However, 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, 45 09 09 (450909)
- Zeiss Axiolab Pol, 45 09 10 (450910)

I was not able to confirm this, but in my opinion it is very likely that the focusing rack from the Zeiss Axiolab microscope also fits the following microscopes:
- Zeiss Standard 20
- Zeiss Standard 25 ICS
- Zeiss Axiostar
- Zeiss Axioskop 20
It may also fit the inverted microscope Zeiss Axiovert 25.

The teeth of this rack can be damaged quite easily, because the whole rack is made of soft brass - and it runs against a hard steel pinion.

Description of this part for the microscope.

The large gear wheel transfers the movement from the shaft that the user turns with the knobs - and on the smaller pinion runs the brass toothed rack (https://www.microscopeparts.eu/part/99943), raising and lowering the stage with the specimen.

In the Zeiss Axiolab microscope these wheels are mounted on the housing casting on a relatively thin axle (it is included in the set offered here), and even the slightest bend of that axle makes the gear turn unevenly.

This gear wheel was removed from a Zeiss Axiolab re microscope, P/N 45 09 05 (also written as 450905). However, 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, 45 09 09 (450909)
- Zeiss Axiolab Pol, 45 09 10 (450910)

I was not able to confirm this, but in my opinion it is very likely that the focusing gear wheel from the Zeiss Axiolab microscope also fits the following microscopes:
- Zeiss Standard 20
- Zeiss Standard 25 ICS
- Zeiss Axiostar
- Zeiss Axioskop 20
It may also fit the inverted microscope Zeiss Axiovert 25.

Lettering: white "Zeiss" wordmark in the typeface introduced together with the joint logo of both Zeiss companies (Zeiss Oberkochen and Carl Zeiss Jena) in 1993/94
Material: aluminium, thin sheet with embossed lettering
Colour: the so-called early light blue, used by the manufacturer until 1997
Dimensions: 23 mm x 23 mm
Mounting: the plate is glued on

This is the plate variant with the logo introduced in 1993/94 and in use until 1997: light blue, a square with the lens cut out at the bottom, lettering in rounded letters. You can see the previous version here: https://www.microscopeparts.eu/part/99868.

Because the adhesive that held these plates to the microscope body loses its grip over the years, such plates sometimes fall off. Sometimes they are also deliberately prised out. A plate like this lets you bring your microscope back to its factory appearance using original parts.

Description of this part for the microscope.

Zeiss Axiolab microscopes - as in most microscopes of the Axio series (among others Axioskop, Axioplan, Axiophot) - the stages are not permanently fixed with screws. They are interchangeable and are fitted onto the stage carrier, which has the form of a clamp. So that the stage can be fitted onto such a carrier, the stages have a dovetail ring on the underside, with a diameter matching the carrier.

Here I am offering exactly such a dovetail ring, removed from the underside of the Zeiss 453510 stage (the number is also written as: 45 35 10).

Basic data of this mounting ring:
Diameter: 98 mm
Width of the ring: 9 mm
Height (how far it stands out above the stage surface): 6 mm
How it is fixed to the bottom plate of the stage: with 4 screws
Removed from: the mechanical XY stage Zeiss 45 35 10
Which microscope this stage worked with: the Zeiss Axiolab re 45 09 05 microscope

The stage this ring comes from was mounted in a Zeiss Axiolab re microscope, P/N 45 09 05 (also written as 450905). However, the same stage model is also mounted on 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, 45 09 09 (450909)
- Zeiss Axiolab Pol, 45 09 10 (450910)

This item is not a spare part for repairing a microscope. It is a component of the microscope stage - and the stage can be used with any microscope onto whose stage carrier a stage with a 98 mm mounting ring can be fitted.

In a separate section, visible below, I describe a few possible uses for this ring.

Basic data of these guides:
Number of guides in the set: 2
Material: the guides are made of plastic
Number of bearing balls: 10 per guide
Length of the guide: 43 mm
Removed from: the mechanical XY stage Zeiss 45 35 10
Which microscope this stage worked with: the Zeiss Axiolab re 45 09 05 microscope

Important: these are not transverse guides. The guides I am offering here are responsible for moving the stage surface back and forth. These guides are not responsible for moving the specimen holder sideways.

The stage these guides come from was mounted in a Zeiss Axiolab re microscope, P/N 45 09 05 (also written as 450905). However, the same stage model is also mounted on 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, 45 09 09 (450909)
- Zeiss Axiolab Pol, 45 09 10 (450910)

This item is not a spare part for repairing a microscope. It is a component of the microscope stage - and the stage can be used with any compatible Zeiss microscope, and even with others, onto whose stage carrier such a stage can be fitted or screwed on.

Detailed photos of these guides are available in the gallery. Every photo shows a scale with a millimetre division. The last photo shows the whole Zeiss 453510 microscope stage, with an arrow pointing at the component in question and at where it sits in the stage, so that this part can be identified without any doubt.

Description of this part for the microscope.

microscope stage, allowing precise movement of the specimen in both the X and Y axes of the stage surface. The manipulator consists of two coaxial knobs and two coaxial drive shafts - an outer one and an inner one, ending in separate pinions of different diameters.

This particular manipulator was removed from the Zeiss 453510 microscope stage (the number is also written as: 45 35 10). The last photo in the gallery shows the whole stage it comes from.

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 are very often damaged mechanically while the microscope is being transported. Because they stick out beyond the outline of the stand, they are the first to take the energy of the impact when the instrument falls or is packed badly.

In many cases it is not the whole manipulator that gets damaged, but only one of its parts. Most often these are the knobs, the drive shafts, the coaxial sleeves or the fixing elements. That is why this database also holds all the most important components of this (and other) manipulators, offered separately as service parts.

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 the XY movement can be fitted. Such a solution works at low magnifications, but when working with objectives above 40x (for example 60x, 63x, 80x or 100x) precise movement of the specimen by hand becomes very difficult. At total magnifications above roughly 400x even a small movement of the hand shifts the image by a considerable distance in the field of view. The mechanical manipulator allows very smooth, controlled and repeatable movement of the specimen in both axes, which matters especially during observation with oil immersion and when making photographic documentation.

The stage this manipulator comes from was mounted in a Zeiss Axiolab re microscope, P/N 45 09 05 (also written as 450905). However, the same stage model is also mounted on 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, 45 09 09 (450909)

This is the rack that works together with the outer (larger) pinion of the stage manipulator (https://www.microscopeparts.eu/part/99973) and is responsible for moving the stage surface in the front-back axis.

Basic data of this rack:
Length of the rack: 55 mm
Number of teeth: 35
Material: plastic
How it is fixed: with 2 hex socket screws, which are included
Removed from: the mechanical XY stage Zeiss 45 35 10
Which microscope this stage worked with: the Zeiss Axiolab re 45 09 05 microscope

Important: there are two racks of different length in the Zeiss 453510 microscope stage. The one I am offering here is the shorter one, responsible for the longitudinal movement, that is for moving the stage surface back and forth. This rack is not responsible for moving the specimen holder sideways.

The stage this rack comes from was mounted in a Zeiss Axiolab re microscope, P/N 45 09 05 (also written as 450905). However, the same stage model is also mounted on the following variants:
- Zeiss Axiolab drb KT, which carries the same number 45 09 05 (450905)

Description of this part for the microscope.

This is the rack - the longer of the two in the stage - that works together with the inner pinion of the stage manipulator (https://www.microscopeparts.eu/part/99973), that is with the pinion of smaller diameter, and is responsible for moving the specimen holder with the spring clip sideways.

Basic data of this rack:
Length of the rack: 80 mm
Width of the rack: 12 mm
Number of teeth: 59
Material: brass (this matters, because the shorter rack is made of plastic)
How it is fixed: with 2 screws, which are included
Removed from: the mechanical XY stage Zeiss 45 35 10
Which microscope this stage worked with: the Zeiss Axiolab re 45 09 05 microscope

Important: there are two racks of different length in the Zeiss 453510 microscope stage. The one I am offering here is the longer one, made of brass, responsible for the transverse movement of the specimen holder. This is not the shorter plastic rack responsible for moving the stage plate in the front-back plane.

The stage this rack comes from was mounted in a Zeiss Axiolab re microscope, P/N 45 09 05 (also written as 450905). However, the same stage model is also mounted on the following variants:
