Zero lenses
Zero lenses have a convex and a concave side with the same radius of curvature: r = r1 = –r2. The transmitted beam has the very long focal length:
With additional plano-convex lenses, the transmitted and reflected beam can be focussed to the same point similar to cavity lenses.

Cavity lenses are positive meniscus lenses, designed for collinear pumping. Back focal length (BFL) is equal to the second radius of curvature:
Cavity lenses are optically designed for 514 nm, but can be used in the range 200-2500 nm without significant differences.
