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.

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.

Description of this part for the microscope.

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.

microscope head mount.

This lens was removed from a Carl Zeiss ICM 405 microscope. Note that the database also contains a Telan lens removed from the twin model, the Carl Zeiss IM 35 (here: https://www.microscopeparts.eu/part/99301). 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 Zeiss IM 35 and Zeiss ICM 405 microscopes were also sold under the Opton brand.

The last photos in the gallery show the Zeiss ICM 405 microscope and a scan of the design diagram from the instruction manual. An arrow on these images indicates where this lens is located in the microscope. This allows unambiguous identification of this part.

ring fitted, which compensates for the refractive error of one eye and lets you focus the image correctly. The tube without diopter adjustment is here: https://www.microscopeparts.eu/part/91069.

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

This tube fits the binocular heads:
- Zeiss 473016 (also written: 47 30 16-9901)
- Zeiss 473012 (also written: 47 30 12-9901)
- Zeiss 473011 (also written: 47 30 11-9901)
- 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.

In the last photo, an arrow shows where this element is located inside the head, allowing precise identification.
