Vacuum tubes assimliate the advanced 3 layers of sputtering deposition of trivalent element technology, high borosilicate glass, gradual change of ALN/ALN-SS/CU selective complex absorptive coating. And these make vacuum tubes have high performance of absorptance and low reflection ratio. Through the interlayer, vacuum has a unique effect of thermo, with its temperature up to 380 Celsius degree of ideal sunning, performing a strong heating ability.
