Re: me again asking for cheap alternative: Objectives

I saw <20 USD worth of objective lens (made in China). I was wondering if you had tried any of them? What are your thoughts? Also, in general, what do you consider in choosing/buying a new objective lens. (I am using Olypus CX 23, and I want to buy 20x or 60x objectives. :D ) Stay safa, happy viewi...

Re: poor sharpness + contrast using 40X on self prepared slides

It's a possibility also that the RI of the mountant is a mismatch and perhaps too close to that of the subject? It may be worth trying an oil-immersion objective, which mitigates coverslip mismatches. As would if you have one, a dry objective with a coverslip correction collar. The judicious use of ...
