Drum lenses
Precision in one dimension
We manufacture high-quality optics and micro-optics for applications that require maximum accuracy. Precise centering turns our optical spheres into drum lenses, which are used in fields such as medical technology and laser technology. They enable extremely precise light focusing along an axis. By using selected raw materials from leading manufacturers such as Schott, Ohara, CDGM, Sumita and Corning, we ensure consistently high quality.
