Bi-convex lenses


Bi-convex 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.Material : BK7 and othersFocal length tolerance :±2% ~ ±0.5%Diameter tolerance :±0.2mm ~ ±0.05mmCenter Thickness :±0.2mm ~ ±0.03mmSurface quality :60/40 ~ 10/5Surface accuracy:λ/4@633nmCentration :3'~1'Bevelling :
