Problem: LOMO EPI objectives have different parfocal height, so you need to adjust focus after switching microscope head to other objective.
Solution: this set makes all objectives parfocal (45mm height), so switching requires micro adjusting only that is much more convenient.
Tested on LOMO Lumam microscope. Works fine.
Made of anodized aluminium. Each extender is marked accordingly to an objective it is purposed for.
Use spaces to separate tags. Use single quotes (') for phrases.
Happy with this set Review by Walter
Many thanks for another great product from RafCamera that offers the user for the first time the possibility to use this set of Epi Objectives parfocal. Finishing is absolutely first-class, and I'm happy to add them to my Russia made Lomo Lumam microscope.
Besides that I really appreciate you encourage your customers to think creative, combined with your anticipation and impressive technical knowledge that leads to amazing new and extremely useful products. (Posted on 10/20/2014)
