VIS-EXT Coated Double-Concave (DCV) Lenses

×
  • AR Coated to Provide <0.5% Reflectance per Surface for 350 - 700nm
  • Designed for 0° Angle of Incidence
  • Precision Diameter and Centration Tolerances Allow for Easy OEM Integration
  • Additional AR Coating Options Available: Uncoated, MgF2VIS 0°VIS-NIRNIR I, and NIR II

TECHSPEC® VIS-EXT Coated Double-Concave (DCV) Lenses are designed to have two inward curved surfaces and a negative focal length similar to Plano-Concave (PCV) lenses. These lenses can be used for balancing aberrations created by other lenses within a system due to their negative spherical aberration. Plano-Concave (DCV) lenses are commonly used in a variety of applications including image reduction, beam expansion and telescopes. TECHSPEC® VIS-EXT Coated Plano-Concave (DCV) Lenses offer optimal performance in the 350nm to 700nm range. These lenses are also available Uncoated, MgF2VIS 0°VIS-NIRNIR I, or with NIR II AR coating options.
