Among the many microlenses produced by II-VI are the C-lens and D-lens types, which are widely used for collimating or coupling beams after the fiber. Our C- and D-lenses are specifically designed for fiber optics applications such as collimators, isolators, switches, collimator arrays, and laser assemblies. Compared with other gradient-index lenses, C-lenses have several advantages, including low cost, low insertion loss in long working distances, and a wide working distance range. With more than 10 years of experience in the lean production of microlenses, II-VI can provide high-volume C- and D-lenses in diameters ranging from 1 mm to 3 mm.
