  • AR Coated to Provide <0.7% Reflectance per Surface for 750 - 1550nm
  • Double-Concave Lenses Have Two Inward Curved Surfaces and a Negative Focal Length
  • Used for Image Reduction and to Spread Light
  • Various Coating Options: Uncoated, VIS-EXT, MgF2, VIS 0°, VIS-NIR, and NIR I

TECHSPEC® NIR II 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® NIR II Coated Double-Concave (DCV) Lenses offer optimal performance in the 750nm to 1550nm range.  These lenses are also available in Uncoated, VIS-EXT, MgF2, VIS 0°, VIS-NIR, or with NIR I AR coating options.
