  • Description
  • Specifications

Plano-convex spherical lenses are positive focal length optical elements that have one plano and one spherical convex surface. These lenses are usually used to collimate, collect and focus light. It is the most cost-efficient choice, when used in infinite-conjugate applications. In order to minimize spherical aberrations, collimated light should be incident onto the convex surface of the lens. 4Lasers offer various focal length plano-convex spherical lenses made from BK7 and UV grade fused silica glass material.
