Bi-convex Lens/Double Convex (DCX) Lens, custom

  The Bi-Convex Lens has large range of lengths and are the optimum shape for producing real images at 1:1 magnification.It is considered for application in preference to a single plano-convex lens if the magnification lies in the region -5<-0.2. It's also widely used in telescope, collimators, optical transceivers, magnifiers, radiometers and condensers.


 Microwork can offer various customized optical bi-convex / double convex (DCX) lenses according to customer requirements. Special cutting lenses such as rectangle, step are available as well.


    Main material of custom bi-convex / double convex lens: BK7 glass, UV fused silica, Corning 7980, JGS1, Sapphire crystal, Quartz crystal, Germanium ( Ge ) monocrystal , Silicon Monocrystal, ZnSe, Barium Fluoride ( BaF2 ), Calcium Fluoride ( CaF2 ), ZnS, Pyrex, BOROFLOAT, float glass, etc.
