Product Details

AR Coated to Provide <0.5% Reflectance per Surface for 600 - 1050nm
Designed for 0° Angle of Incidence
Various Coating Options: Uncoated, VIS-EXT, MgF₂, VIS 0°, VIS-NIR, and NIR II

TECHSPEC® NIR I 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 I Coated Double-Concave (DCV) Lenses offer optimal performance in the 600nm to 1050nm range. These lenses are also available Uncoated, VIS-EXT, MgF₂, VIS 0°, VIS-NIR, NIR I, or with NIR II AR coating options.

Anti-Reflection (AR) Coatings

Anti-reflection (AR) coatings are applied to optical components to increase throughput and reduce hazards caused by back-reflections.
