This objective was removed from a Leitz Dialux microscope, but it is compatible with most Leitz Wetzlar microscopes manufactured approximately before 1980 (SM, SM-Lux, Dialux, Ortholux, Orthoplan, etc.).

Some useful information about Leitz Wetzlar objectives with TL=170 mm and FL=37 mm:
- most Leitz microscopes manufactured approximately before 1980 support both 160 mm and 170 mm tube length objectives
- many Leitz microscopes support both 37 mm and 45 mm focal length objectives
- by adding an RMS-8mm adapter, such an objective obtains a focal length of 45 mm. Leitz manufactured such adapters under the name "Plezzy" - however, many users make their own versions from metal or by using 3D printers

# Examples of use
- If you have a microscope without objectives and need to restock it using original parts
- If you have a microscope that doesn't have an objective lens with this magnification and want to restock it
- If you have such an objective lens, but it's of very poor quality or damaged
- If you want to keep such an objective lens as a spare
