Achromatic lens is designed to limit the effects of chromatic and spherical abberation. It is corrected to bring two wavelengths(typically red and blue) into focus in the same plane. Achromatic lenses can be doublets or triplets, with two or three individual glasses cemented together. Material--------------------BK7 Grade A or equivalent optical glasses Design Wavalength-------480-650nm Diameter Tolerance-------í+0.1mm, í+0.15mm for Dia.í¦75mm Paraxial Focus Length-----í+2% @546.1nm Centration-----------------80% Surface Figure-------------ª-/4 @632.8nm Surface Quality------------60-40 scratches and dig Coatings-------------------Antireflection coatings or NIR coatings Bevel-----------------------A slight protective bevel (For different applications, there are various choices in the specifications, which must be determined according to users specific requirements.) Products include: Achromatic lens Meniscus Lens Double-concave Lens Plano-concave Lens Double-convex Lens Plano-convex Lens Cartons
Achromatic lenses are normally made of BK7, fused silica and CaF2. Special focusing systems can be designed by Photonchinaâ??s engineer team. Sizes from smallest diameter of 3mm to biggest of over 100mm are all available. Normal Achromatic Lens Super Small Achromatic Lens Super small Achromatic Lenses for your specific application provide excellent wavefront quality, super small spot size and improved modulation transfer function (MTF). Feature Small diameter size up to 3mm Short focal length, such as 5mm Strict quality control, excellent quality AR-coating, mounts services
