B270 glass is produced by Schott group in Germany. B270 is a glass model commonly used for high-end filters. B270 has very high transmittance and hardness. It is one of the best optical glass materials. At present, B270 glass is generally used as the best filter in the market
B270 glass: it is a colorless, high transmittance coronal glass melted from high-purity raw materials. Its main feature is to maintain high transmittance in the ultraviolet and infrared bands.
B270 glass has the characteristics of high stability to sunlight and high transmittance in the visible light range. In addition, it also has highly stable thermal and chemical properties. It is widely used in digital projectors, touch screens, vacuum coated substrates and so on.
