Best Form Spherical BK7A Lens (BFCX)

  • Best Form produces smallest spot size for a singlet lens

Plano-convex lenses are useful for a wide range of applications. These lenses are manufactured from UV transmitting Fused Silica, CaF2, MgF2 or BK7A for visible applications. All lenses are uncoated but Anti-reflection coatings are available. When used to focus a collimated beam, the light should be incident on the curved surface of the lens. These plano-convex lenses may be combined with other lenses to form complex imaging systems.
