Working Principal
Vacuum tubes assimilate the advanced 12 layers of spattering deposition of trivalent technology, high borosilicate glass, gradual change of SS-CU-AlN/ALN selective complex absorptive coating. And these make vacuum tubes have high performance of absorptance and low reflection ratio. Through the inter layer, vacuum has a unique effect of thermo, with its temperatureup to 380℃ of idle sunning. performing a strong heating ability.
