This purple guy is for sale on e-bay, the seller has five of them : Mitutoyo Objective Lens M Plan Apo NUV 20x /0.40 ∞/0 f=200
I don't need the near UV correction - but, will this work just as well as a 'normal' 20x for stacking, the working distance is given as 17 mm, which should be fine for my purposes.

Re: Mity 20x NUV usability?
It's probably going to be worse corrected for visible light than a normal 20x, with lower resolution and shorter wd. But I imagine it would still be an above average objective.

Thank you Scarodactyl, that's what I wanted to know.

Re: Mity 20x NUV usability?
I know nothing of objective lenses other then what I picked up in this forum, but from what I remember used Mity's are often spotty, so buying a used UV one for 1000USD when the "proper" version cost 2000 new sounds risky.
strange thing when looking up the prices:
edmund sells the UV version for 6500USD while on the mitutoyo website they are listed for around 4000
https://www.edmundoptics.com/p/20x-mitu ... tive/6838/
https://shop.mitutoyo.eu/web/mitutoyo/e ... 72C6A5C7E0
on the other hand, the normal version is roughly the same (2000) on both:
https://www.edmundoptics.com/p/20x-mitu ... tive/6625/
https://shop.mitutoyo.eu/web/mitutoyo/e ... ndex.xhtml
might be that I got confused about the exact versions though.
