Color temperature insulating filter glass
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.
