Customer-specific spherical optics for complex systems and assemblies

Spherical Optics.

Exceptional Imaging and Beam Quality.

We produce spherical optics for your most demanding applications in imaging and multi-spectral systems (e.g.: digital aerial cameras) as well as in LASER-based technologies (e.g. femtosecond lasers, high-energy lasers, 193nm optics…).
