This is description of this part:
Manufacturer: Lomo (Russia, after 1991)
Model: AU-12 export version without manufacturer's name
Color: newest, white
Magnification: 1.5x
Eyepieces: 23.2 mm
Mounting: 41 mm dovetail (Carl Zeiss Jena standard)
The head features adjustable interpupillary distance and diopter adjustment for one eyepiece.
This export version was sold in Western Europe, primarily under the Bresser brand. Biolam microscopes were sold under this name (thus as Bresser Biolam). NOTE - a small batch of these microscopes was sold under the Bresser Erudit name - but the "Erudit" is now a completely different Bresser microscope.
This is an exact clone of the Carl Zeiss Jena microscope head and is therefore very commonly used for these microscopes.
Note: The 1.5x magnification head requires a relatively large amount of light. Furthermore, the optimal image is obtained with 7x or 8x eyepieces (the maximum is 10x). Higher eyepiece magnification results in "empty magnification" and the image may not be sharp.
What is this part needed for?
- if you have a microscope without a microscope head
- if you have a monocular head and want to upgrade your microscope
- if you have a binocular head, but it is damaged or of very poor quality (e.g., it has delamination on the prisms)
