Double-Concave Lenses are used in beam expansion, image reduction, or light projection applications. These lenses are also ideal for expanding the focal length of an optical system. Double-Concave Lenses, which have two concave surfaces, are Optical Lenses with negative focal lengths.
Realpoo Optics offers double concave lens, and they are available in several anti-reflection coating optics, including MgF2, VIS 0°, VIS-NIR, NIR I, or NIR II, for optimal performance in the Ultraviolet (UV), Visible, or Infrared (IR) regions.
