タイトルまたは説明

1.Single target vacuum tubes Features Single target sputtering plating Structure: all glass double-tube coaxial structure Material: high borosilicate glass 3.3 Al-N/Al absorb coating Capabilities: Fast thermal collecting efficiency High heat resistance Super cold resistance Specific absorption: As= 0.***0.*3(AM1.5) Average heat loss coefficient: 0.**0.7W/m²oC 2, Hightech Three-target tubes 3 target sputtering plating Structure: all glass double-tube coaxial structure Material: high borosilicate glass 3.3 Interferential coating: Cu/Ss-ALN/ALN compound absorb coating Capabilities: Fast thermal collecting efficiency High heat resistance Super cold resistance Specific absorption: As= 0.***0.*6(AM1.5) Average heat loss coefficient: 0.**0.6W/m²oC 3. Triple-Cavity Tubes Features Adding one more complete glass tube in the normal tube, increasing the heating efficiency by decreasing the water content but not the heating ***** heating efficiency can be increased *0% by this way. Structure: all glass coaxial dual-tube, an inner tube into a dual-glass outer tube Material: high borosilicate glass 3.3 Thermal collecting efficiency increased *0%
