The same objective model was also sold under the name "Leica" instead of "Leitz" on the housing, so these are in fact identical objectives. This objective also fits Will Wetzlar microscopes.
What is this part needed for?
- if your microscope lacks a 40x phase contrast objective
- if you have a 40x PHACO2 objective damaged or in poor condition
- if you have a microscope from any manufacturer that supports TL=160 FL=45 objectives, this is also a lens for you
