Double-Convex Lenses

Double-Convex Lenses, also known as DCX or Biconvex lenses, are used in image relay applications, or for imaging objects at close conjugates. Double-Convex Lenses have positive focal lengths, along with two convex surfaces with equal radii. Aberrations will increase as the conjugate ratios increase. DCX Lenses are used in a range of industries or applications.

Edmund Optics offers a wide variety of Double-Convex Lenses in a range of substrates or anti-reflection coatings for maximum performance in the Ultraviolet (UV), Visible, or Infrared (IR). Anti-reflection coatings include UV-AR, UV-VIS, MgF₂, VIS 0°, VIS-NIR, NIR I, or NIR II. UV Fused Silica or Calcium Fluoride (CaF₂) substrates are also available for additional performance in the Ultraviolet (UV) or Infrared (IR) spectrums. UF Fused Silica Double-Convex Lenses are ideal for close conjugate imaging systems utilizing Ultraviolet (UV) illumination. Calcium Fluoride (CaF₂) offers a very wide transmission range of 350nm - 7μm. Edmund Optics’ Double-Convex Lenses are available in a wide range of diameters or focal lengths.
