Even though this is a phase contrast lens (Quod - Ph DM QM), it can also be used for standard brightfield work.
What is this part needed for?
- If you have a SWIFT microscope without objectives and need to restock it using original parts
- If you have a SWIFT 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
