This is description of this part:
Eyepiece tube with a 23.2 mm eyepiece seat for a Carl Zeiss microscope binocular head (Oberkochen, West Germany).
This is the tube without a diopter adjustment ring. The tube with the adjustment is here: https://www.microscopeparts.eu/part/91070.
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, trinocular and photo heads included.
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)
- and of course check that the mounting diameter of your eyepieces is 23.2 mm
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.
The last photo has an arrow showing where this part sits in the head, so you can identify it without any doubt.
What is this part needed for?
- very often this tube is dented and an eyepiece cannot be inserted
