Compared to many other forms of optical lenses, Concave Meniscus Lenses are rarely offered off-the-shelf. While meniscus lenses are primarily used for focusing to small spot sizes or collimation applications, plano convex lenses often offer a superior price-to performance ratio. There are scenarios, though, where meniscus lenses provide significantly superior performance at only a moderate increase in price.
