Description Features Tables Metrology
Biconvex lenses are used as magnifiers, objectives, condensing systems. Since both surfaces contribute to the power of biconvex lenses, they have shorter focal length than PCX lenses of equal diameter and surface radius. Under customer request anti-reflection or other types of coatings can applied.
varna Converges incident light
varna Lower spherical aberrations than for Plano-Convex lenses
varna Ideal for Experimenting and Prototyping Applications
