This page will list microscope objectives with numerical aperture higher than a typical achromat; most of them probably immersion-type. The goal is to inform people on which lenses are out there at specific mags and which require corrections outside the objective itself e.g. in eyepiece.

While I spent a lot of effort composing them, these tables are guaranteed to be incomplete.
