This is description of this part:
The BSM/SM Greenough stereomicroscope line includes a large number of models, manufactured since the 1920s. Objective lenses are mostly compatible and interchangeable between models. Some (older) objective lens versions are similar to the one in my offer, while others are black-housing (but internally identical). However, they can be interchanged between models.
What is this part needed for?
- if your stereo microscope doesn't have such a lens
- if you have one, but it's damaged or of very poor quality
- if you need a professional 2x lens for DIY super-macro photography
