UV Fused Silica for 230-1600nm applications
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.
