This is description of this part:
Microscope objective for older microscopes (so-called antique, vintage).
Manufacturer: Hertel & Reuss
Magnification: 100x
Model: Oel immersion
Thread: RMS
Tubus length: 170 mm (?)
Focal length: 37 mm
Immersion: yes, oil
The optics (lenses) in this microscope objective are in very good condition.
There's no manufacturer's marking on the objective lens. Because lenses from different manufacturers looked very similar at the time, I'm not sure whether Hertel & Reuss manufactured the lenses themselves or ordered them from another company (e.g., Leitz). Therefore, these lenses can be safely used with microscopes from many other manufacturers.
What is this part needed for?
- Primarily for people who want to complete their incomplete vintage microscope with period parts
- if your microscope lacks a 100x objective
- if you have a 100x objective damaged or in poor condition
- if you want to start in super-macro photo stacking
- if you have a microscope from any manufacturer that supports TL=170 FL=37 objectives, this is also a lens for you
