When lights are needed to focus or diverge in systems, lenses are used.
For different applications in various industries, single or cemented lenses of different shapes are designed, including plano-convex (PCX) or double-convex (DCX) lenses causing lights to focus, plano-concave (PCV) or double-concave lenses making lights diverge after passing through them, cemented lenses realizing aberration correction, ball lenses enjoying short back focal lengths (BFL), cylindrical lenses making lights form a line, condenser lenses collecting lights, aspheric lenses correcting spherical aberration and other more types.
Chenter supplies lenses made of various materials, including optical glass (Fused Silica, N-BK7, N-F2, N-SF4 …) and crystals (Ge, CaF2, MgF2, Al2O3, Si, ZnSe …).
Upon requests, standard and customized coating options are available, ranging from ultraviolet (UV), visible (VIS), to Infrared (IR) wavelength.
