TECHSPEC® NIR II Coated Plano-Concave (PCV) Lenses are designed to bend parallel input rays to diverge from one another on the output side of the lens causing this lens to have a negative focal length. These lenses can be used for balancing aberrations created by other lenses within a system due to their negative spherical aberration. Plano-Concave (PCV) lenses are commonly used in a variety of applications including image reduction, beam expansion and telescopes. TECHSPEC® NIR II Coated Plano-Concave (PCV) Lenses offer optimal performance in the 750nm to 1550nm range. These lenses are also available Uncoated, VIS-EXT, MgF2, VIS 0°, VIS-NIR, YAG-BBAR, or with NIR I AR coating options.
