This is description of this part:
Collector lens for illumination in the Leitz Wetzlar Dialux 20 microscope. The lens is housed in a plastic mount which also serves as a filter holder.
This lens is part of the component shown in the Leitz Dialux 20 microscope manual under number 18, which corresponds to the field diaphragm assembly. This page from the manual can be found in the image gallery.
The field diaphragm of the Leitz Dialux 20 microscope consists of:
- lens
- iris diaphragm
and is screwed to the microscope base (stativ foot) directly below the condenser.
The item offered here is exactly this lens.
This lens performs several functions:
- it collimates the light beam
- it protects the iris diaphragm from contamination
- it also serves as a filter holder for inserting filters
It is worth noting that this element may also be compatible with many other Leitz Wetzlar microscope models.
