Using three targets in DC magnetron sputtering technology based on the reaction, rare metals, improve the target, vacuum coating structure of working temperature can reach 500 degrees Celsius, service life is longer. Compared with common vacuum tubes, this product has high temperature, high absorptivity of 96% (heat), low loss (4%) can be low to the advantages in alpine environment, XiaJi thermal effect also significantly.

At the same time, the international leading microwave zijin vacuum technology and craft, in 49 ° C for 50 minutes of strict exhaust, automatic getter evapotranspiration process, heat loss. Vacuum for 15 years, maintain gas molecules to avoid tube heat insulation, significantly.
