Novoflex

... novoflex's 0.2um number sounds great to me, but I'd expect that to be rather optimistic (ie marketing) numbers. should work up to very high magnifications. also, novoflex does provide the thing as a fully featured integrated system, so it should be useable straight of the box. that also means t...

In contrast, the wavelength range of the normal 10x apo is 435nm-655nm. .... I don't know how bad they will be, but there must ...

Lou, perhaps I said it not clear enough: I'm, for myself, not interested in the near UV correction / blue light at all and did not point to the correction of the blue light. I just wanted to explain, that the...

... Yes, the spectral range is bigger than that of the ordinary Mitutoyo lenses, but the range is also shifted toward the IR end of the spectrum. Lou, if I try to read it critical AND if the wording in the Mitu description is not just plain / fooling advertising -- for "our" normal use of light in ...
