Baoguang vacuum tubes adopt dry absorb type selective coating with lower remittance,is solved the problems of normal tubehaving not good curve of emittance,when the temperature higer,the remittance higer,which reduce the efficiency of the vacuum tube.Three Higher Points of this new tube:
1)Higher efficiency:the absorbance increased by 14% with remittance reduce by 30%-40%
2)Higher heat conduction:Dry exposure temperature up to 270Cand can endure -30%environment temperature and still working.
3)Higher vacuum degree:Unique technology to keep vacuum degree,stable absorbance which guarantee the long life of the tube
Customized specification is welcome!
