Best Form Spherical Lenses are double-convex (DCX) lenses designed with asymmetrical faces to achieve the smallest possible spot size with spherical surfaces. Featuring 10-5 surface quality and utilizing UV Fused Silica substrates, these lenses are an alternative to laser grade aspheric lenses. With common diameters and various focal lengths available, these lenses can easily be integrated into optical systems requiring precise focusing. Best Form Spherical Lenses are optimized to reduce spherical aberration and far exceed performance of plano-convex (PCX) lenses without the cost associated with aspheric lens designs. These lenses are ideal for precise laser applications where the large aperture diffraction limited performance of an aspheric lens is not needed.
