In our setup, a plano-convex would have less than half as much SA as a double convex lens. A meniscus would be about half of that, and it's the only one for which the SA is constant throughout the entire zoom range. So a meniscus is clearly the best choice. Taking these factors...

The optimum lens for on-axis vision was biconvex, with the more curved surface facing the cornea. For small off-axis angles, optimum lens shape varied with the ocular parameters. A recommended range of intraocular lenses is plano-convex (with the curved shape facing the cornea) to equi-...

To replicate the key optical physics of JWST's three-mirror anastigmat (TMA) design at optical wavelengths we have developed a three-lens anastigmat optical system. This design uses custom lenses (plano-convex, plano-concave, and bi-convex) with fourth-order aspheric terms on powered surfaces ...
A combined micro-objective lens for optical disc use has been developed. The lens consists of a thin relief diffraction grating film and a planoconvex glass substrate. The combined lens, which is called the spherical grating lens (SGL), is inherently a spherical lens, but has some interesting...
