Lenses with achromatic function

Spherical lenses, also known as round optics or spheres, are used to collect, diverge or focus light. They are used for various technological applications, for example in medical technology and  semiconductor industry, or as a component in achromatic lens systems. Achromatic lenses consist of two to three lenses cemented together. This combination generally serves to reduce spherical aberration.

Thanks to modern manufacturing technologies, we are able to produce spherical lenses of high quality and from different materials. In addition to optical glasses, these include crystals such as germanium and silicon, metals, PMMA and IR materials. For ideal use, we also finish your spheres with high-quality optical coatings, depending on the application. asphericon manufactures spheres with diameters from 8 mm to 300 mm and shape accuracies down to the nanometer range, customized to your requirements.
