This is description of this part:
Monocular microscope head with adjustable tube tilt angle for eyepieces with a 23.2 mm mounting diameter.
This model of microscope head was used as a projection head in Carl Zeiss Jena Pictoval projection microscopes (microprojectors). The adjustable tilt angle of the eyepiece tube, which held a projection eyepiece (usually f=100), allowed the position of the projected image on the projection surface to be changed.
Basic parameters:
Manufacturer: Carl Zeiss Jena
Eyepiece mounting diameter: 23.2 mm
Mounting to the microscope arm: 41 mm diameter dovetail ring
Because this microscope head has a Carl Zeiss Jena standard microscope mount (a 41 mm diameter dovetail ring), it can be mounted on most microscopes from this manufacturer (e.g. Carl Zeiss Jena Eduval, Laboval, Ergaval, Amplival, etc.), as well as on microscopes made by Lomo (e.g. Lomo Biolam), IOR and Meopta.
It seems useful to mention a few points:
- never look through this microscope head with the naked eye if a projection eyepiece is installed in it and the head is mounted in a Carl Zeiss Jena Pictoval microprojector. This may result in loss of eyesight due to the very high light output emitted by this microscope
- when mounting this microscope head on a microscope other than a Carl Zeiss Jena Pictoval, a different magnification scale may be obtained than with the original heads designed for the particular microscope model
- projecting a microscope image requires a great deal of light, i.e. a powerful illuminator. This is worth remembering if you intend to use this head to project an image from biological microscopes with standard incandescent illumination (e.g. 15 W 6 V), which is definitely not sufficient
- visual observation using this microscope head may be inconvenient because it has a different (smaller) tilt angle than standard monocular or binocular microscope heads
What is this part needed for?
- if you have a Carl Zeiss Jena Pictoval microscope without its original projection head
- if you want to use such a microscope head with another Carl Zeiss Jena microscope or with a microscope made by another manufacturer
