Spherical lenses are relatively easy to manufacture but have disadvantages such as spherical aberrations in many optical applications. Aspheric lenses have clear advantages here – they avoid spherical aberrations due to their principle and can therefore reduce the complexity of both the design process and the resulting optical system. However, the cost and effort involved in the traditional production of aspheric lenses, e.g. using diamond turning, has often prevented the use of this type of lens in cost-sensitive applications. GH Optics manufactures aspheric lenses by molding glass preforms in molds of high precision. The result is affordable aspheric lenses with high, reproducible quality. In addition to a wide range of standard types (see below), GH Optics also manufactures custom aspheric lenses. So if you don’t see the aspheric lens you need in our catalog, we can have it custom built for you. Our optical experts help you defining the best solution and GH Optics’ engineering team can manufacture at off-the-shelf lens prices that you won’t find elsewhere.
