VIS-NIR Coated Double-Concave (DCV) Lenses

×
  • AR Coated to Provide <1.25% Reflectance per Surface for 400 - 1000nm
  • <0.25% Reflectance @ 880nm
  • Designed for 0° Angle of Incidence
  • Various Coating Options: Uncoated, VIS-EXTMgF2, VIS 0°, NIR I, and NIR II

TECHSPEC® VIS-NIR 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. Double-Concave (DCV) lenses are commonly used in a variety of applications including image reduction, beam expansion and telescopes. TECHSPEC® VIS-NIR Coated Double-Concave (DCV) Lenses are optimized for transmission (>99%) in the near-infrared. These lenses are also available Uncoated, VIS-EXTMgF2VIS 0°, NIR I, or with NIR II AR coating options.
