Deep Ultra-Violet (DUV) Polarizers and Phase Plates
The operating wavelength can be selected as short as 250nm in the deep UV range. Due to their inorganic nature, our polarizers and phase plates are very resistant to high-power light input, even in the DUV range.

Half-Mirror Polarizer for Laser Cavity
Reflectivity for each polarization can be tuned separately. As a half-mirror in a laser resonance cavity, the element is used to generate and select the output polarization of the laser. Because of its inorganic nature, the element can withstand very high optical power.

Custom Polarizer & Phase Plates
Our products can be customized not only for the optical properties, but also for the shape and the spatial distribution of those properties. In particular, they can be made non-uniformly, having a segmented structure or a curved axis along the surface. Pease feel free to discuss any exotic design you may need for your application!
