B270 Glass

B270 glass is ultra-white glass, an ultra-transparent low-iron glass. B270 is very pure, with high stability to sunlight and high transmittance in the visible range. The light transmittance rate is up to 91.5%, which is known as the “crystal prince” of the glass family. In addition, it has highly stable thermal and chemical properties. B270 sheet can be cut into many different standard thicknesses and can be mechanically and optically polished. If surface quality is not critical, it can be used without surface treatment. The B270 can be used to make precision optical quality instruments.
