What is this part needed for?
- if you have a Steindorff Berlin microscope and want to use this condenser
- if you want to use this microscope element in a microscope from another manufacturer with a 39.5 mm condenser mount
- if you want to assemble a fully equipped microscope with as many accessories as possible and this condenser model is missing from your set
- if you want to replace your current condenser with N.A. < 1.4 to achieve better resolution with higher quality objectives
