Absorptive Glass
Scroll down
Cevians has developed unique high-performance absorptive glass composition. The high phosphate, RoHs and REACH compliant materials are formulated, melted, cut, and polished using our proprietary processes. We currently have 16 formulations which all provide specific absorption from the UV to NIR spectrum.
Molded to Perfection
The glass can be fabricated to sheet form or molded to specific geometries. They are primarily used for custom applications where the performance of commercially available glass is not sufficient. This includes narrow band absorption in specific wavelengths, where the diffusion and refraction index is precisely controlled.
Finished to Custom Specifications
Glasses are finished to custom specifications and can be produced in small and large scale volumes.
