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.

This turret mounts with a dovetail joint, allowing you to quickly swap out entire sets of objectives without having to unscrew them individually if you have more than one turret.
This allows you to have a complete set of low-power objectives on one turret and a complete set of high-power objectives on the other, quickly swapping them as needed.

The dimensions, the function it performs and my knowledge of the design of both microscope models lead me to believe that both lenses are identical - but since they were physically removed from two different microscope models, they are listed separately in the database.

The photos show the dimensions and exact appearance of this component from various angles. The first photo also shows the lens's precise position within the microscope.

drive" automatic film advance.

Important: this is the so-called "extended cable" intended for cameras with automatic film advance (the so-called Winder). The standard cable for cameras without a Winder carries the Zeiss part number 47 17 84 - 0000 (or, in later revisions, with the suffix -9901).

This cable connects the dedicated electrical system connector located at the lower front of the Zeiss ICM 405 inverted microscope body to the camera control socket. It carries the shutter release signal from the microscope's side control panel as well as the return signals from the automatic exposure system and the exposure meter (integrated with the ASA/DIN slider, P/N 47 17 71). Unlike the standard version, this model of cable contains additional signal lines. After an exposure, it sends a control pulse to the camera's motor-drive (Winder), causing the film to advance automatically to the next frame without the microscope user having to touch the camera.

In the last photograph in the gallery, an arrow indicates the connector on the Carl Zeiss ICM 405 microscope into which this cable is plugged.

Important: the connector on the front of the Zeiss ICM 405 is not a standard PC Sync connector (used for ordinary flash units), but a proprietary multi-pin Zeiss system connector.

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.

interface into which the microscope head is inserted and secured. It makes no difference whether a binocular or trinocular microscope head is mounted in this fitting.

- the inner diameter of this microscope head mount is 44 mm
- this mounting ring is attached to the microscope stand with three screws
- the ring has two small screws that both center and secure the microscope head, as they engage with the dovetail groove of the microscope head
- thanks to these screws, microscope heads with a dovetail diameter from 42.5 mm to 44 mm can be mounted in the ring
- the main spring-loaded clamping screw

This head mount was removed from a Carl Zeiss ICM 405 microscope, but it is also suitable for the IM 35 model.

the microscope body (see the last photo in the gallery). It is a replaceable component - the manufacturer provides various adapters for connecting different cameras at this location.

Basic parameters of this adapter:
Manufacturer: Carl Zeiss (Oberkochen, West Germany)
Catalog number: 47 17 78 (another notation: 471778)
Mounting to the microscope body: 50 mm diameter dovetail ring
Camera mounting to the adapter: ring with a 70 mm inner diameter
Clamping screw: yes, there is a screw for securing the camera

This camera mount was removed from a Carl Zeiss ICM 405 microscope, but it fits any microscope with a compatible mounting interface. It originally had an analog Zeiss M35 camera mounted in it.

The photos show the dimensions and exact appearance of this component from multiple angles. Additionally, the last photo shows the Zeiss ICM 405 microscope with an arrow indicating where this component is located on the microscope. This allows the component to be accurately identified and located.

The Carl Zeiss ICM 405 inverted microscope is an advanced version of the Carl Zeiss IM 35 inverted microscope. The main differences between the ICM 405 and the IM 35 are the ICM 405's more advanced microphotography capabilities.

However, many users treat these two models as essentially the same microscope and use the name "Zeiss IM 35" for both, sometimes only specifying that it is a "Zeiss IM 35 with photo output".

Both models were also sold under the Opton brand, in which case they are respectively called Opton IM 35 and Opton ICM 405. Users often refer to them as a "Zeiss Opton microscope".

Description of this part for the microscope.

Mechanically, this photo tube is mounted inside the microscope body, below the microscope head mount. It splits the light beam (image) travelling through the microscope head and eyepieces to the user's eyes. Part of the light beam is directed to the universal photo output.

Basic parameters of this photo tube:
Manufacturer: Carl Zeiss (Oberkochen, West Germany)
Catalog number: 47 17 72 (other notation: 471772 or 471772-9901)
Mounting to the microscope body: the tube is mounted inside the microscope, with only the adjustable output extending to the outside (a simple tube)
Camera mounting to the adapter: a straight tube with an inner diameter of 35 mm extends from the side of the microscope body. The outer diameter of the mounting section is approx. 39 mm
Focus adjustment: yes, the tube has a helical focusing ring for precise focus adjustment
Light beam splitting mode: the light beam is split (it is not 0/100 or 100/0), unfortunately I do not know the percentage of the light split (no documentation available)
Light-splitting element: partially reflecting beam-splitting mirror (not a cemented prism block)

This photo tube was removed from a Carl Zeiss ICM 405 microscope. However, it is a completely universal light-splitting tube, so with suitable DIY mounts it can be used in practically any microscope or other optical device (astronomical telescope, binoculars, spotting scope, spectrophotometer, etc.). The universal interface for connecting an image-recording device (a straight tube with a 35 mm inner diameter) allows, among other things, the use of digital cameras or DSLR cameras (with suitable adapters). Since the light beam is split, this output can be used for "simul-focal live" observation, meaning that in real time the same image can be seen simultaneously through the microscope eyepieces and by the camera.

The photos show the dimensions and exact appearance of this component from multiple angles. Additionally, the last photo shows the Zeiss ICM 405 microscope with an arrow indicating where this component is located on the microscope. This allows the component to be accurately identified and located.

Note: In one discussion on the Mikroskopie-Forum.de forum, it is mentioned that this tube was also used in Carl Zeiss Axiomat microscopes. The user refers to this component as "Zeiss 47 17 72-9901 Kino- und TV-Anschluß", but I do not have documentation for this component and therefore cannot confirm this.

without lenses used for? When working with low power objectives (roughly up to 10x - 12.5x), a better image is obtained
- either without any condenser
- or with an iris diaphragm only
- or with a special condenser of very low numerical aperture N.A.
This solution is very often used in inverted biological microscopes - and that is exactly how the condenser shown here was used.

If this were a complete condenser with optics (which it is not), the Zeiss microscope condenser P/N 465267 (also written as 46 52 67) could be fitted with N.A. 0.32 top lenses, with DIC or polarization top lenses N.A. Apl. 0.63, or with others, because the top lens is an interchangeable element screwed into the condenser housing.

The item shown here can be described as:
- a Zeiss condenser housing
- a Zeiss iris diaphragm in a housing
- also (although not correctly) a condenser with N.A. of about 0.20
However, since this is not a damaged item, it has the thread into which a condenser top lens can be screwed.

In Carl Zeiss microscopes of the Standard series (except the Standard Junior school model), the condenser is not mounted in a round holder. It has a ring-shaped dovetail that slides into the dovetail guide of the condenser carrier.

The last photo in the gallery shows the Carl Zeiss ICM 405 inverted microscope, with an arrow indicating exactly where this particular condenser was mounted.

The Zeiss 465267 condenser has a mount in the form of a dovetail ring. This mounting interface is used, among others (this is not a complete list), in the following microscope models:
- Zeiss Standard 14 / 16 / 18 / GFL
- Zeiss Standard WL / WL 89
- Zeiss Standard 20 / 25 / 25 ICS
- Zeiss Universal
- Zeiss Photomicroscope I / II / III RS
- Zeiss Ultraphot
- Zeiss IM 35 / ICM 405 inverted microscopes

The mounting ring of the condenser shown here has a diameter of 41.6 mm. The ring also has a factory-made conical notch that fits the locking pin fixing the position of the condenser. This pin is located in the condenser carrier.

Note on the mounting diameter: over nearly 50 years of production of microscopes of this series, the dovetail diameter was always about 42 mm - but it was not perfectly constant. Depending on the year of production, the material (plastic, aluminium, brass) and the type of condenser (classic Abbe or phase contrast turret condenser), it can range from slightly above 41 mm to almost 43 mm. Such a large tolerance results from the design of the condenser carrier: it has return springs, a locking pin and clamping / centering screws. Thanks to this, condensers with a mounting ring diameter of 41 to 43 mm can almost always be mounted stably.

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.

Basic parameters:
- Type: tube with diopter adjustment ring
- Diameter of eyepieces accepted: 23.2 mm
- Color: black

This tube fits the binocular heads:

- Zeiss 473013 (also written: 47 30 13-9901)
and probably others, as Zeiss often used the same components in several head models.

Before fitting this tube into your own head you should above all:
- check the shape of the tube foot. For example, there is also a polarizing variant of the head, Zeiss 47 30 12-9902, in which the eyepiece tube seat has a different shape (you can see it here: https://www.microscopeparts.eu/part/00536)
- check how many screws hold it to the head
- check all the dimensions (the photos show a millimeter scale)

This is a service part for a microscope binocular head - not for one particular microscope model. Such a head can be mounted on many Zeiss microscope models (and even on microscopes from other makers), so no list of microscopes this tube fits can be given - it fits the head, and the user mounts the head wherever they want.

Description of this part for the microscope.

IM 35 and Zeiss ICM 405 inverted microscopes, focusing is done by raising and lowering the nosepiece with the objectives. To make that possible - the nosepiece sits on a shaft that travels out of and back into the inside of the microscope body through an opening in the housing. To keep dirt from reaching the mechanism by that same route - the opening is protected with a rubber seal.

This is exactly the seal I offer here, together with its mounting plate.

The same nosepiece movement mechanism and the same way of keeping dust out with a rubber seal are used in the Zeiss Axiovert 10 / 35 / 405 M inverted microscopes - but whether the seal from the IM 35 / ICM 405 models fits those, I was not able to confirm. It is quite possible - but before you decide to use this seal on an Axiovert series microscope - compare its shape and dimensions carefully (a millimetre scale is visible in the photos).

Over the years this rubber seal often gets damaged, and then you can either fit something improvised - or replace it with an original, which, as in this case - is only available on the secondhand market.

The last photo in the gallery shows the body of the Zeiss IM 35 microscope, with an arrow pointing to where this rubber seal sits in the microscope. This allows the part described here to be identified beyond any doubt.
