Product Description
Three target high vacuum tube
1.Vacuum tube feature:
The kind of vacuum tube assimilate the advanced 12 layers of spattering deposition of trivalent element technology, high quality borosilicate glass 3.3, gradual change of CU-SS-ALN/ALN selective absorption coating and make vacuum tubes have high performance of absorptance and low reflection ratio. Through interlayer, vacuum has a unique effect of thermal, with its temperature up to 380 degree of idle sunning, performing a strong ability.
2. Vacuum tube specification:
47-1500MM, 58-1800MM (Standard specification)
47-1800MM, 58-2000MM (optional specification)
3. Vacuum tube Loading quantity in container:
47-1500MM, 4700 PCS/20ft, 9600 PCS/40ft.
