Patented technology

We design and manufacture space-variant retarders (SVR) using patented direct laser writing technology. This advanced technique enables the formation of self-organized periodic nanostructures, so-called nanogratings, within the bulk of fused silica glass.

Exceptional accuracy

These nano gratings exhibit tailored birefringent properties that can be precisely controlled during fabrication, offering five degrees of freedom: spatial positioning, retardance, and the orientation of the birefringence axis.As a result, we produce a range of flat optical elements capable of manipulating light's polarization, phase, or amplitude with exceptional accuracy.
