Product Description

Characteristics：
Vacuum tubes assimilate the advanced 12 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 absorption and
low reflection ratio. Through the interlayer, vacuum has a unique effect of thermo, with its temperature up to 380℃ of idle
sunning, performing a strong heating ability.
