Plano Convex Lens – BK7A (PCX)

  • BK7 for Visible Near IR applications
  • Focal length designed at 633nm
  • Focal Length: f = R/(n-1)
  • n: refractive index
  • R: radius curvature

Plano-convex lenses are useful for a wide range of applications. These lenses are manufactured from BK7A for visible and Near IR 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.
