  • Description
  • Specifications

Plano-convex spherical lenses have one plano and one spherical convex surface, while their focal lengths are positive. These lenses provide best performance when used for 5X to infinite-conjugate ratio applications, e.g. focusing a collimated light beam or collimating beam from a point source.
