temicon is supplier of aspherical lenses. Such lenses show a refractive or reflective surface, there shape is different compared to ideal spherical surfaces. Mathematically, aspherical lenses can be described by equations of second, third and/or higher orders. Such lenses are designed to minimize optical imaging errors. The orientation of aspherical lenses could be concave or convex. Similar to spherical lenses, an individual arrangement or an array of aspherical lenses (microlens array, MLA) is possible.
