Plano Convex Spherical Lenses UV Fused Silica (PCX)

  • UV Fused Silica for 230-1600nm applications
  • The focal length is designed at 250nm
                 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 Corning 7980 0F grade for 230nm to 1600nm 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.
