Plano-concave spherical lenses «In Stock»

Plano-concave spherical lenses have one plano and one spherical concave surface, while their focal lengths are negative. These lenses provide best performance when used for 5X to infinite-conjugate ratio applications, e.g. collimating a convergent beam, diverging a collimated beam. To prevent spherical aberrations collimated beam should always be incident on curved lens surface and vice versa.
