This lens is often used with Leica microscopes (e.g., the DMLB, DMLS, or DM1000 models). It is often shorter than Leica objectives, but an extension adapter is used in these cases.
What is this part needed for?
- Jenamed or Jenalab microscopes often don't have a 20x objective lens installed.
- If you have one, but it's of very poor quality or damaged.
- If you're cautious and want to have one as a spare.
