The ultraviolet band is currently mainly used in the semiconductor industry. Borisun keeps up with the development of the national semiconductor industry. Based on the technical accumulation of the company’s founding team when they worked in research institutes and foreign companies, we can provide customers with 193nm, 254nm, and 355nm ultraviolet-induced filters, ultraviolet reflectors and other products.
