Bi-convex Spherical Lenses

Bi-Convex Lenses, or, “Equi-Convex” are utilized for finite imaging.  They are ideal for positive conjugate image ratios from 0.2 to 5 and are most suitable when the object and image are at equal distances from the lens.  Spherical aberration is minimized and because of their geometry, other aberrations and distortions are also minimized.   OptoSigma’s lineup consists of N-BK7 and Fused Silica both uncoated and AR coated options.   Can’t find what you need?  Ask us to modify a stock lens for quick delivery, or, send us requirements for a complete custom solution.
