I recently purchased an eBay microscope with this objective attached. It was not parfocal with the rest of the objectives, so I set up an experiment to find out about the characteristics:
- M26
just less than 1mm FOV, so probably 20X
approx 30mm working distance
seems distortion free on an Eclipse 200 infinity microscope
I'm wondering what the possibility is that this is a Mitutoyo Plan Apo 20X?
I know there are other Mitutoyo clones, and the WD is not 20mm like I see on eBay, so I'm a bit perplexed.
Would this objective have any use in a macrophotography application?
Thanks Aidan
