After installing the 12 mm adapter, this objective lens will have FL = 45 mm.
What is this part needed for?
- 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're cautious and want to have a spare objective lens
