Zeiss IM 35 (IM-35, IM35) microscope is the Opton ICM 405 (ICM-405, ICM405).

Please note that exactly the same (!) illuminator is also used on the Zeiss Standard / Photomicroscope series microscopes. Please refer to the description of illuminator No. 99684 in this database. YES – these are exactly the same illuminators. However, that particular unit was removed from a Zeiss Photomicroscope II and therefore has its own separate description. You will also find additional photographs and an extended description there.

illumination according to the Koehler standard
- slot for inserting the illuminator
- angled mirror reflecting the light beam

Important - some versions have a base with a removable illumination collector module with a field diaphragm. This base has this module permanently mounted (screwed), but there is no difference in operation between these versions.

Important - the base does not include the illuminator. The Standard GFL model uses illumination with a 6V 15W bulb mounted in a holder (Lampenfassung). This illuminator is connected to an external transformer. It is a separate component and is not included with the base.

a Zeiss microscope stage on which no model designation was provided. Over the years during which Zeiss produced such stages, numerous variants were created (I have personally seen five, for example Zeiss P/N 47 34 28 - 9901 https://www.microscopeparts.eu/microscope/282). Despite this variety, the construction is largely consistent, and most parts are identical.
It is therefore highly likely that the part shown and offered here is compatible with many variants of such microscope stages.

Such stages are interchangeable and can be installed in many Zeiss microscopes, however they are most commonly used in the following microscopes:
- Zeiss Standard 14
- Zeiss Standard 16
- Zeiss Standard GFL

Also often in:
- Zeiss Standard WL
- Zeiss Standard Universal

Note that there are two such guides in the stage. They are made of a soft, thin piece of brass sheet and are often damaged; the bearing rollers also frequently fall out of them.

In the photo gallery there are detailed photos of this element together with the dimensions.

This lens provides an excellent, wide image, and because it doesn't require a cover glass, it's often used for macro photography and stacking.

Important - this lens is not suitable for taking photos using the "direct-projection" technique, as it requires plan-compensation optics.

A microscope objective with such low magnification is used, among others, in the following fields:
- tissue overview examination in pathomorphology
- observation of insects
- observation of minerals
- observation of inclusions in amber
- handwriting analysis
- observation of micromollusks
- and many others

This particular screw was removed from a Zeiss Standard 14 microscope, but it will most likely fit most models of the Standard series, for example:
- Zeiss Standard GFL
- Zeiss Standard 16
- Zeiss Standard WL 89
- Zeiss Standard Universal
- Zeiss Standard Photomicroscope
- Zeiss Ultraphot

Note - over the years, Zeiss microscopes (or the same microscopes sold under the Zeiss-Winkel name or under the Opton brand), especially simpler models such as the Zeiss Standard Junior, used different types of head-retaining screws. These were not necessarily spring-loaded screws - in some cases ordinary threaded clamping screws were used instead.

Before deciding to replace the screw in a microscope, it is best to carefully compare its appearance and dimensions with the photographs in the gallery or ask a question on the forum https://www.mikroskopie-forum.de/

field lens (Zeiss P/N 47 30 68). It can be installed in the tube between the objective nosepiece and the observation head. The lens is operated by a lever protruding from the side of the tube. In the manufacturer's documentation, this lever is referred to as "Switch to turn axis, e.g. with wide field changer 0.8x-1x". If this optional microscope component is not installed, the opening intended for the lever is closed with a plastic blanking plug additionally secured by a retaining screw. This listing includes exactly that end cap and screw.

This particular cover was removed from a Zeiss Standard 14 microscope, which is not normally equipped with the lever-operated lens. However, it will most likely fit the majority of other Standard series models, for example:
- Zeiss Standard GFL
- Zeiss Standard 16
- Zeiss Standard WL 89

The blanking plug itself carries the catalog number Zeiss 47 30 65 (alternative notation: Zeiss 473065) and is described as an "intermediate tube cover element".

Not only is this plastic cap frequently lost over the years, but the lever itself or the lens assembly may also become damaged and require removal. In such cases, this blanking plug should be installed to protect the microscope optics from dust.

In the last photographs in the gallery, I use arrows to show exactly which microscope component is being offered and where it is located within the microscope.

supply:
Manufacturer: Carl Zeiss
Model: NAG 6V 20W stab.
Catalogue number: 45 84 15 - 9901
Input: 100-120-230-240 V
Output: 6 V
Output power: two outputs. It can supply either 2 × 10 W or 1 × 20 W
Power connector: separate computer-type power cable
Potentiometer: yes, smooth adjustment

This power supply has a maximum output power of 20 W and provides two outputs, allowing two 10 W illuminators to be connected and operated simultaneously.

However, it is a universal power supply and can be used with any microscope illuminator using a light source (lamp) rated at up to 20 W and operating at 6 V. Since most Zeiss microscopes use 6 V 15 W lamps, this power supply is suitable for virtually every microscope equipped with such illumination.

This power supply is most commonly used with microscopes employing 6 V 10 W halogen lamps, where both the transmitted-light illuminator and the reflected-light EPI illuminator are connected to the same power supply. Examples include:
- Zeiss D / DR / DRC / SV (Stemi) stereo microscopes
- Zeiss KF-2 biological microscope
- Zeiss ID2 inverted microscope

Special illuminators designed to work with this power supply were even manufactured for the Zeiss D / DR / DRC stereo microscopes:
- transmitted-light base "Zusatz für Durchlicht" with a 10 W halogen lamp
- auxiliary illuminators "Leuchte 10" / "Leuchte 10 S" with a 10 W halogen lamp
- vertical illuminator "Epileuchte" with a 15 W incandescent lamp

"Leuchte 10S" illuminators on a flexible arm, together with this particular power supply, are frequently used as a source of side reflected illumination for the Zeiss KF-2 biological microscope.

Examples of other microscopes whose 6 V 15 W illumination is compatible with this power supply:
- Zeiss Standard 16 / WL / GFL
- Zeiss Universal / Photomicroscope
- PZO Biolar
- PZO MST-130 / 131
- Carl Zeiss Jena Ergaval / Amplival
- Carl Zeiss Jena SM-xx
- this power supply can also be used externally to power the halogen illuminator of Carl Zeiss Jena Jenamed microscopes if the internal power supply fails (Jenamed uses a 6 V 20 W halogen lamp)

Note – different manufacturers and different illuminators may use different pin spacing in their 6 V connectors. It may therefore be necessary to modify the connector in order to connect it to this Zeiss power supply.

Description of this part for the microscope.

In Carl Zeiss Standard series microscopes (with the exception of the Standard Junior teaching microscope), the condenser is not mounted in a circular clamp. Instead, it is fitted with a circular dovetail ring that slides into the condenser mounting guide.

This mounting interface is used on, among others, the following microscope models:
- Zeiss Standard 14 / 16 / 18 / GFL
- Zeiss Standard WL / WL 89

The ring has a diameter of 41.3 mm and three mounting holes used to attach it to the condenser. It also features a tapered recess that engages with the locating pin in the condenser holder, ensuring correct positioning of the condenser.

When attached to a condenser made by another manufacturer, this ring makes it possible to use, for example, the PZO KPI-2 DIC condenser and dozens of other condensers on Zeiss Standard-class microscopes.

Note regarding the mounting diameter: during nearly 50 years of production of this microscope series, the dovetail diameter was always approximately 42 mm, but it was never exactly identical. Depending on the production year, the material (plastic, aluminium or brass), and the condenser type (classic Abbe condenser or phase contrast disc condenser), the actual diameter may range from just over 41 mm to almost 43 mm. This relatively large tolerance is a consequence of the condenser holder design. The holder incorporates spring loading, a locating pin and centring/locking screws. As a result, condensers fitted with a mounting ring between approximately 41 mm and 43 mm in diameter can almost always be mounted securely and remain well centred.

Basic parameters of this phase annulus:
Manufacturer: Carl Zeiss (Oberkochen, West Germany)
Condenser marking: "2"
For objectives: marked "Ph2", i.e. magnifications from 16x to 40x
Material: glass mounted in a metal retaining ring with flange
Outside diameter of the retaining ring: 22 mm
Phase annulus glass diameter: 16 mm
Height of the retaining ring: 3.5 mm

Important: this microscope component (phase annulus / phase diaphragm) is not intended for any specific microscope model. It is a component used to upgrade or repair a microscope phase contrast condenser. It is not intended for upgrading or repairing one specific condenser model. Many Carl Zeiss condenser models have a suitable opening into which this phase annulus can be inserted.

This particular phase annulus was removed from a fluorescence phase contrast condenser — an older version of the Zeiss condenser P/N 46 52 78. Before installing it in your condenser, carefully compare the shape of its housing and the dimensions of the retaining ring.

- Zeiss Standard 14 / 16 / 18
- Zeiss Standard WL / WL 89
- Zeiss Universal
- Zeiss Photomicroscope (Zeiss PM / Phomi – all models)
- Zeiss Ultraphot

In these microscope models, the condenser has a dovetail mounting ring. This dovetail includes a notch into which the spring-loaded screw presented here engages. You can see what this mounting ring looks like and how the notch is shaped in the photo gallery of item No. 99625 in this database.

This filter holder accepts filters with a diameter of 32 mm.

This is not only a replacement service part used when the original filter holder has been damaged (for example, if the spring tab or retaining latch has broken). Many owners of Carl Zeiss Standard microscopes modify their microscopes by attaching another (additional) filter holder to the condenser holder. This is exactly the component required for such a DIY modification.

This filter holder can also be attached to the condenser holder of the following microscopes:
- Zeiss Universal
- Zeiss Photomicroscope
- Zeiss Ultraphot
However, these microscope models were originally equipped with a different type of filter holder.

The last photographs in the gallery show examples of use — this filter holder fitted with a blue filter and with a DIY insert made using a 3D printer.

Basic parameters of this clear glass insert:
Manufacturer: Carl Zeiss (Oberkochen, West Germany)
Material: glass mounted in a metal retaining ring with flange
Outside diameter of the retaining ring: 22 mm
Diameter of the clear glass disc: 16 mm
Height of the retaining ring: 3.5 mm

Below are some example applications for this clear glass blank. It can be printed or fitted with, among others:
- a phase annulus or darkfield annulus matching the original one that was installed in the condenser but has become damaged
- an annulus missing from the condenser
- coloured Rheinberg rings
- oblique illumination diaphragms producing a DIC-like effect
- a Hoffmann modulation contrast pattern
- phase annuli for objectives made by other manufacturers, for example Carl Zeiss Jena PhV
- any completely custom DIY design

This particular clear glass ring insert was removed from a fluorescence phase contrast condenser — an older version of the Zeiss condenser P/N 46 52 78. Before installing it in your condenser, carefully compare the shape of its housing and the dimensions of the retaining ring.

Interchangeable diaphragm carriers (whether for phase contrast or, for example, darkfield) make it possible to configure a phase contrast condenser exactly as required. This allows the condenser to support precisely the observation techniques and microscope objectives needed.

The clear glass blank presented here is not a component intended for any specific microscope model. Instead, it is used to upgrade or repair a microscope phase contrast condenser. Likewise, it is not dedicated to any specific condenser model. Many Carl Zeiss condenser models have a suitable opening into which this complete insert can be fitted and customised with your own pattern.

This particular holder complete with the wide field lens was removed from a Zeiss Standard GFL microscope, but it also fits condenser holders used, among others, in the following microscopes:
- Zeiss Standard 14
- Zeiss Standard 16
- Zeiss Standard 18
- Zeiss Standard WL / WL 89

The lens can be removed from its holder (as shown in the accompanying video) and used for other DIY projects. The very fact that it is removable (and sometimes even falls out by itself) is the reason why it is missing from many used microscopes. The component offered here is intended to solve exactly this problem.

Replaceable diaphragms (both for phase contrast and darkfield) for phase contrast condensers allow the condenser to be configured individually. Thanks to this, it can support exactly the observation techniques and exactly the microscope objectives that are required.

Important: by installing the fluorescence-polarization diaphragm presented here, a condenser currently equipped with standard phase contrast diaphragms can be upgraded with this unique function. A detailed description of the capabilities offered by this technique is provided below.

Basic parameters of this phase contrast diaphragm:
Manufacturer: Carl Zeiss (Oberkochen, West Germany)
Condenser marking: "2". On the Zeiss condenser P/N 46 52 78 this position is marked in blue
For microscope objectives: to obtain phase contrast operation, use microscope objectives marked "Ph2", i.e. objectives with magnifications from 16x to 40x
Substrate material: glass mounted in a metal holder with a flange
Ring material: polarizing film
Outside diameter of the retaining ring: 22 mm
Glass disc diameter: 16 mm
Retaining ring height: 3.5 mm

Important: this component (phase contrast annulus / phase contrast diaphragm) is not intended for a specific microscope model. It is a component for upgrading or repairing a microscope phase contrast condenser. It is not intended for upgrading or repairing any specific condenser model. Many Carl Zeiss condenser models have a matching opening into which this phase contrast annulus can be installed.

In the Carl Zeiss condenser P/N 46 52 78, the phase annuli in positions 2 and 3 are not ordinary openings in an opaque mask but openings in a polarizing film. The polarization direction of these annuli is N-S, so the direct light beam that forms the phase contrast image is linearly polarized. Since it is polarized, its intensity can be adjusted continuously with a second polarizer – without any mechanical parts, diaphragms or shutters.

This second polarizer can be any pair of rotatable polarizing filters. In the original Zeiss design, this is the Carl Zeiss light control unit P/N 47 72 20 with two independently rotatable polarizers mounted beneath the condenser. This makes it possible to switch on phase contrast while simultaneously reducing the illumination intensity to a safe level.

- when the polarizer is aligned parallel to the N-S axis of the annulus – full transmission, maximum phase contrast beam, full-strength phase contrast image;
- when the polarizer is crossed (E-W) – the annulus "goes dark", the objective phase plate no longer receives the direct beam, and the phase contrast image disappears;
- when the polarizer is set to intermediate positions – smooth adjustment of the contribution of the phase contrast image.

When the illumination source is a fluorescence lamp (or, of course, an LED FL light source), simply rotating the polarizer beneath the condenser (together with removing the excitation filter) allows the user to switch from a fluorescence image to a conventional phase contrast image. With the polarizer crossed and the excitation filter installed, the phase annulus is extinguished and only pure fluorescence is visible; as the polarizer is rotated, the phase contrast image gradually increases and is superimposed on the fluorescence image. The second polarizer in unit P/N 47 72 20 is additionally used to attenuate the overall illumination intensity (to protect the specimen or to control the specimen's exposure to fluorescence light).

And now an interesting note from the Ultraphot-shop website https://www.microscopeparts.eu/(http://www.the-ultraphot-shop.org.uk/bicolor.htm), © Spike Walker 2007:

Because the annulus is a linear N-S polarizer, it can be used to produce coloured phase contrast: when a two-colour polarizing filter (Cokin type) is placed between the microscope polarizer and the condenser annulus, the specimen takes on the colour of the illuminating annulus against the background colour of the remaining part of the disc – for example, an orange specimen on a green background when using a red-green filter.

This particular phase contrast annulus was removed from a fluorescence phase contrast condenser – an older version of the Zeiss condenser P/N 46 52 78. Before deciding to install it in your condenser, carefully compare the shape of its housing and the dimensions of the retaining ring.

These stages are most commonly fitted to the following microscopes:
- Zeiss Standard GFL
- Zeiss Standard 14 / 16 / 18

This is a component of the microscope stage rather than a component dedicated to a specific microscope model. Since this stage can be used on many different microscope models, this specimen holder is likewise compatible with numerous Carl Zeiss Standard series microscopes.

The gallery photographs show the exact dimensions of this component and its mounting holes. The final photographs additionally show the complete microscope stage from which this specimen holder was removed. An arrow indicates the exact stage component being offered, making visual compatibility easy to verify. The accompanying video also demonstrates the operation of the spring-loaded specimen clamp.

are equipped with a base illuminator using a 6 V 15 W lamp. This can be replaced with:
a) a large 60-watt illuminator using a 12 V 60 W lamp
b) a halogen illuminator

This listing presents the illuminator described in option a), namely the 60 W incandescent lamp version.

Basic specifications of this illuminator:
Manufacturer: Carl Zeiss (Oberkochen, West Germany)
Model: 60-watt illuminator
Lamp voltage: 12 V
Lamp house mounting method: circular dovetail
Cooling: passive. The entire large lamp house also serves as a heat sink, dissipating the heat generated by the 60-watt lamp
Lamp socket centering screws: yes, the lamp socket is equipped with centering screws
Diffuser: yes, inside the lamp house, in front of the lamp condenser lens (the so-called illumination collector), there is a matte diffuser mounted in a flip-out holder

This particular unit was removed from a Carl Zeiss Photomicroscope II. However, it is compatible with most microscopes of the Zeiss Standard series.

This illuminator fits the following microscopes:
- Zeiss Standard 16 / GFL
- Zeiss Standard WL / WL 89
- Zeiss Universal
- Zeiss Photomicroscope
- Zeiss Photomicroscope II
- Zeiss Photomicroscope III RS
- and also the Zeiss IM 35 / ICM 405 inverted microscope

The following is a quotation from the Zeiss Photomicroscope II instruction manual:

60-watt illuminator

Instead of the 6-v. 15-w base illuminator, the 60-watt illuminator may be firmly connected to the microscope stand. For this purpose, the collector tube with lamp condenser, 46 70 50, must be removed after unscrewing the bottom plate and replaced by the connecting tube, 46 70 41 (Fig. 15). The 60-watt illuminator is mounted in the usual manner with the aid of a dovetail ring, like a body tube, for example.

The variable transformer is identical to the one for the base illuminator and supplies voltages from 0 ... 20 volts. When this equipment is used, the red scale of the voltmeter applies.

Several important points should be mentioned:
- if your microscope is currently equipped with the standard 6 V 15 W illumination system, the illuminator mounting adapter must also be replaced (this is described in the instruction manual quoted above)
- the lamp house of this illuminator is finished in grey. Some Carl Zeiss Standard series microscopes have black, cream or hammered-finish housings. This illuminator is mechanically compatible with those models, although the colour may not be an aesthetically perfect match
- power supplies with a rated output of exactly 60 W are virtually unavailable on the second-hand market. In practice, 12 V 100 W power supplies are used to operate this light source
- please note that exactly the same (!) illuminator is also used on the Zeiss IM 35 / ICM 405 inverted microscopes. Please also refer to the description of illuminator No. 00697 in this database. YES – these are exactly the same illuminators. However, that particular unit was removed from an inverted microscope and therefore has its own separate description. You will also find additional photographs there. In the Zeiss IM 35 instruction manual, the lamp socket is referred to as "Lamp socket 60 P/N 46 80 15", while the lamp house is referred to as "Lamp housing with lamp condenser P/N 46 72 27"
- this illuminator can be used for both transmitted-light and reflected-light (EPI) illumination
- if you would like to manufacture your own DIY illuminator mounting adapter because you do not have the original Zeiss part (P/N 46 70 41), the following information may be useful: the circular dovetail on this illuminator has a diameter of 43 mm, which is the same as on many microscope condensers and mono-, binocular and trinocular microscope heads. This means that, for example, a microscope head mounting adapter can be used as the basis for manufacturing a custom DIY illuminator adapter

Important: The photographs show a lamp installed in the lamp socket. This lamp DOES NOT LIGHT because it is burned out. It is shown only so that you can see which lamp model is used in this illuminator.
