The Bi-Convex Lens has large range of lengths and are the optimum shape for producing real images at 1:1 magnification. In a single lens application you should consider using them in preference to a single plano-convex lens if the magnification lies in the region -5<-0.2. It is widely used in telescope, collimators, optical transceivers, magnifiers, radiometers and condensers. Creator Optics can produce various customized optical bi-convex / double-convex lenses according to customer requirements. Cutting lenses like rectangle, step are available. Main material of plano-convex lens: BK7 glass and all catalog optical glass, Sapphire crystal, Quartz crystal, Germanium ( Ge ) monocrystal , Silicon Monocrystal, ZnSe, Barium Fluoride ( BaF2 ), Calcium Fluoride ( CaF2 ), ZnS, Pyrex, BOROFLOAT, float glass, etc. Surface Quality: 80/50, 60/40, 40/20, 20/10, 10/5. Coating: We provide various single layer or multiplayer anti-reflecting ( AR ) coating against differrent requirements. Customized available.
