Description:
Double Convex 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. DCV Lenses are used in a range of industries or applications.
GIAI 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. GIAI Optics’ Double Convex Lenses are available in a wide range of diameters or focal lengths.
Double-Convex (DCX) Lenses have two outward curved surfaces, a positive focal length and are useful for 1:1 imaging and in multi-element systems.
