Problems solved by technology

Due to poor stability, low viscosity and poor crystallization resistance, infrared glass is difficult to be prepared into infrared optical fiber panels by conventional processes
Therefore, the spectral response range of the existing optical fiber panel is between 400-900nm, and it is not sensitive to infrared light above 900nm, which restricts its application range
