Color Temperature Insulating Filter Glass is a kind of color optical glass for surgical light. The color temperature index from 4000k to 5000k and the Color index more than 90. The product is steadiness if it has not hard coat. It has put in mass manufacturing. Hope we can do co-operate successfully.
