Colored Glass Filter & Windows

Color Glass Filter that is directly dyed to the glass has the optical performances that ranks next to the lens by using the features of absorption or transmission of the material and can be used semipermanently due to its excellent durability.

It is used by applying coating treatment to its surface so that the light can be reflected. We secure the stable supply and cost competitiveness through the exclusive supply agreement with the expert supplier of color glass with good quality and reasonable price. Please call our sales division in case you need the material plate and tailor-made size or coating option.
