Produce Information: 

DLL Vacuum tubes assimilate the advanced *2 layers of spattering deposition of trivalent technology, high borosilicate glass, gradual change of ALN/AIN-SS/CU selective complex absorptive coating. Ang 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 **0° C of idle sunning, performing a strong heating ability.
