Thankyou Robert

My best wishes to you,

Christian

... 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...

Robert, great test again -- such a tiny lens with even - visible - better results with...

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 ...

No, for the reasons I just gave. The specs clearly say it is not corrected for blue light. 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...
