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.

and a single line below it reading: Made in West Germany.

This is not the plate for the base of Zeiss Photomicroscope microscopes. Although it looks similar - it is not the plate for the body of the Zeiss Stereomicroscope either.

This plate has two pins on its inner side. The photo intermediate tube should have two holes into which these pins are pressed. For a firmer hold you can apply some glue to the underside of the plate.

In one of the last photos in the gallery you will see two photo-trino intermediate tubes lying side by side. As you can see, this plate is not fitted at the factory on every variant of the intermediate tube.
- I have not come across it (and I have seen no mounting holes) on the black intermediate tubes of the earliest Carl Zeiss Universal, Ultraphot and Photomicroscope models
- on the latest variants of the Photomicroscope III the logo is printed on the base (instead of a plate) and there is no plate on the intermediate tube

Importantly - intermediate tubes can be swapped between models of this class, so the surest way to tell whether this plate fits a particular tube is to check whether it has mounting holes.

Over the years this plate often fell off or was torn off, so on the second-hand market you can find microscopes with this element missing.

Some users like this style of the older models and, after cutting off the two mounting pins, they glue the plate onto a photo intermediate tube that has no mounting holes.

The last photo in the gallery shows several models of this microscope class standing side by side. Arrows mark the ones that carry a logo plate like the one offered here.

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.

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

- check how many screws hold it to the head
- check all the dimensions (the photos show a millimeter scale)
- and of course check that the mounting diameter of your eyepieces is 23.2 mm

Description of this part for the microscope.

the Zeiss Photomicroscope III microscope. The following cables come out of it:
- with a 12 pin plug (2x6)
- with a 22 pin plug (2x10 + 2)

The cable presented here ends with a 12 pin plug, that is 6 rows of two flat contacts each. Marking on the plug: "Siemens DIN41622 VG95322 A12".

The cable was tested before being removed from a working microscope. The plug is fully functional, its plastic housing is neither broken nor crumbled, and all contacts are straight. Attaching / soldering on the base side has to be taken care of on your own.

Several names are used for this microscope model, among others:
- Carl Zeiss Photomicroscope III
- Carl Zeiss Phomi III
- Carl Zeiss PM III
- Zeiss Photomicroscope III RS
- Zeiss Phomi 3
- Zeiss PM3 RS

Replacing this cable can solve, among others, the following problems:
- when the microscope has a cut off cable, which is common when it comes from an institution that scraps electrical equipment this way
- when the microscope has a cable with a plug whose housing is broken, cracked or chipped
- when the microscope has a cable ending in a plug with broken off flat contacts
- when the microscope has a cable in which the plug has a damaged latch

A new plug of this type can be bought today. It is the DIN 41622 standard, a two row arrangement of 3.0 x 1 mm blade contacts, 12 poles - produced continuously for decades and offered today by Telegärtner, Binder, MPE and EVG among others. At Telegärtner the 12 pole male connector carries the number 100023261, and the matching female connector the number 100023250. One has to keep in mind, however, that this is only the contact insert itself: the cable housing (metal or plastic) together with the mounting trough is bought separately, the guide pins that also serve as coding are bought separately, the cable of the right cross section is bought separately, and all twelve contacts have to be soldered. Some users will appreciate owning an original cable with a period plug whose coding matches their microscope, while others will be glad that I have given the designations of the new equivalents and can go their own way.

microscope

This is one of two cables coming out of the base of the Zeiss Photomicroscope III microscope. The following cables come out of it:
- with a 12 pin plug (2x6)
- with a 22 pin plug (2x10 + 2)

The cable presented here ends with a 22 pin plug, that is 10 rows of two flat contacts each plus two single contacts in the middle. In the Zeiss manual the matching socket on the power supply is described as a 22 pole socket for the supply voltages of the automatic exposure control. There is no standard designation on the plug - only the marking "Siemens" and the letter "R" are visible.

The cable was tested before being removed from a working microscope. The plug is fully functional, its plastic housing is neither broken nor crumbled, and all contacts are straight. Attaching / soldering on the base side has to be taken care of on your own.

Several names are used for this microscope model, among others:

- when the microscope has a cable ending in a plug with broken off flat contacts
- when the microscope has a cable in which the plug has a damaged latch

I have not found a new 22 pole plug in the current catalogues of the makers of this blade connector family - this pole count falls outside the range produced today. What remains is the second hand market. An original, working cable with a period plug saves you that search.

repairing the eyepiece.

Lens position: this is the topmost lens of the microscope eyepiece, called the eye lens
Lens construction: this is a cemented lens, flat on one side and convex on the other
Matching eyepiece: this is the lens from the Zeiss West Germany CPL W 10x/18 eyepiece, model number 464022-9901

This lens is not a replacement part for the microscope. It is a part for repairing a microscope eyepiece - and that eyepiece can be used in various microscopes, even from manufacturers other than Carl Zeiss. A few microscopes this eyepiece can be used with are listed in the "compatibility" section, but this is definitely not a complete list. It is safe to assume that the Zeiss CPL W 10x/18 eyepiece can be used with any microscope from any manufacturer whose head has a 23.2 mm eyepiece tube diameter.

the body only, without optics.

What is included: three parts - the lower sleeve that goes into the eyepiece tube of the head, the retaining ring that holds the lenses inside the housing, and the upper sleeve with the engraving
Material: all parts of the housing are made of plastic - this is unusual, because in eyepieces of this class the bodies are normally metal
Marking on the body: ZEISS West Germany CPL W 10x/18, number 464022-9901
Mounting diameter: 23.2mm - a standard eyepiece tube

This housing is not a replacement part for the microscope. It is a part for repairing a microscope eyepiece - and that eyepiece can be used in various microscopes, even from manufacturers other than Carl Zeiss. A few microscopes this eyepiece can be used with are listed in the "compatibility" section, but this is definitely not a complete list. It is safe to assume that the Zeiss CPL W 10x/18 eyepiece can be used with any microscope from any manufacturer whose head has a 23.2 mm eyepiece tube diameter.

The plastic this eyepiece housing is made of can be damaged in various ways. It often cracks, gets scratched, or deforms and partly melts from heat - the proximity of a bulb, a lamp or a soldering iron is enough, and very often the culprit is simply the cigarette held in the same hand that turns the focus knobs. In that case - especially when the optics inside are still intact - you can simply replace the housing with the one offered here.
