From chemistry to components

For over 35 years Cevians has been at the forefront of material and optical components design and manufacturing. We offer over 16 unique glass and 25 polymeric chemistries and have developed 100’s of custom formulations, synthesizing and transforming materials into finished components.

Our expertise includes high-performance thin-film coatings for cutting-edge applications that require harsh environment resistance and demanding performance from UV, visible, NIR, and Infrared. We combine our experience in material sciences and applied engineering for ultimate optical component integrated lighting, optical materials, and electro-mechanical structures.
