I have recently acquired an Olympus BH2, with a rather odd mix of objectives:
- Zeiss Plan 2.5x/0.08
- Olympus SPlan 10x 0.30
- Zeiss Neofluar 40x 0.75
- Zeiss A-Plan 100/1.25 oil (I don't think I have any intention of using this.. we never use 100x at work)
I will probably look out for Olympus D-Plan or S-Plan objectives (20x an 4x) and to replace the Zeiss 40x (which incidentally works ok, but isn't great towards the edge of the field). The Zeiss 2.5x actually works very well.
Random background: I work as a pathologist (currently a trainee), so I spend most of my day at work using a microscope anyway. In spite of this, I (and most pathologists, I believe) know rather little about microscopes!
Many thanks!
