Aspheric lenses

Depending on the size, specifications and number required, aspheres are produced using either the DOC3D^® process or the DOCFast^® process. All conceivable geometries and combinations are possible, , e.g., plan CX/CC, bi CX/CC or CX CC. Typical sizes range from 5 to 120 mm in diameter. Doctan® and Doctan^® SG2, two high-quality types of optical glass especially developed by Docter Optics, can be used with either process.
