K9玻璃/BK7 Glass

K9玻璃是用K9料制成的玻璃制品，K9料属于光学玻璃，由于它晶莹剔透，加工出来的产品，在市面 上称为水晶玻璃制品。K9的组成如下：SiO₂=69.13% B₂O₃=10.75% BaO=3.07% Na₂0=10.40% K₂0=6.29% As₂O₃=0.36%.光学玻璃中的冕牌玻璃，属于硼硅酸盐系统。它的折射率和阿贝数都 很低，价格低廉，微加工性能良好，其光学系数为1.5163,色散是80多，几乎无气泡和杂质，外表清晰无色，由高纯度材料制成。在K9玻璃上制作微米、纳米尺度的微结构和微器件的技术，已应用于光电子、微波技术、衍射光学元件等众多领域。

K9 glass is a glass product made of K9 material. K9 material belongs to optical glass. Because it is crystal clear, the processed product is called crystal glass in the market. The composition of K9 is as follows: SiO2 = 69.13% B2O3 = 10.75% BaO = 3.07% Na20 = 10.40% K20 = 6.29% As2O3 = 0.36%. The brand glass in optical glass belongs to the borosilicate system. Its refractive index and Abbe number are very low, the price is low, the micro-machining performance is good, its optical coefficient is 1.5163, the dispersion is more than 80, almost no bubbles and impurities, the appearance is clear and colorless, and it is made of high-purity material. The technology of making micro- and nano-scale microstructures and micro-devices on K9 glass has been applied to many fields such as optoelectronics, microwave technology, and diffractive optical components.
