Tripe target evacuated tube: 1)High absorbance 2)Resist the frozen weather 3)Cu-Ss-Al absorb coating The tube has the following advantages: 1)Absorptivity:0.***0.*6 because of the copper insulation, the absorption of stainless steel and the decline heat of Aluminium layer. 2)Endure bad weather Our evacuated tube can endure temperature to **0ã��Cï&frac*4;�even under **0ã��C since the vacuum rate can reach less than 5.0Ã�***3pa. 3)Structure stability The tube prssure-endure ability can reach 1Mpa 4) Long life Patented conducting substance is compatible with normal metal material that result in non-condensable gas and non-stop running within *5 years and long duration for the collector. 5) Advanced technology Our company use 3 target magnetron sputtering plating technology, which introduce from Germany and also called interferometer coating technology. We have different diametical tubes, for example, *7mm, *8mm, *0mm of external pipe.
