Vacuum tube
We control strictly all the working procedure from cleaning to exhausting.
Vacuum tube is made of 3.3 high boron silicon glass and has small thermal expansion rate and high intensity.It can resist the impact of hailstone under 25mm.
Advanced technology:
Multi-layer magnetron sputtering gradation aluminum-nitrogen/aluminum sun selective absorption coating improve the heat collecting efficiency of high vacuum tube.
Well material:
with high transmittance,well cold and thermal shock resistance and strong optics stability.
