Description

* Diameter (metric): 12,5 - 50,0 mm * Diameter (imperial): 0.5 - 2 inch * Diameters up to 4 inch available on request * Focal length from 12,7 mm to 1200 mm Biconvex (double convex) lenses minimize spherical aberration as well as cancel coma and distortion at unit conjugate ratio. Biconvex lenses are all symmetrical, having equal radii on both sides. They are recommended for virtual imaging of real objects, and for positive conjugate ratios from 0.2 up to 5. Outside of this ratios range plano-convex lenses are usually more suitable. Biconvex lenses are used as magnifiers, objectives, some condensing systems. Since both surfaces contribute to the power of biconvex lenses, they have shorter focal lengths than plano-convex lenses of equal diameter and surface radius. Lenses can be supplied anti-reflection coated.
