Three Layer Vacuum Tube
It is made by two concentric transparent borosilicate glass tubes (Pyrex) able to resist impact from hail up to 25mm in diameter. The inner glass tube is coated with a selective coating of Al-N/Al, which absorbs and converts the maximum of solar radiation & infrared light into heat and reduces emissivity. A barium getter is used at bottom of the inner evacuated tube. This barium layer actively absorbs all CO, CO2, N2, O2, H2O. The "tube" is one continuous piece with no metal embedded which makes the vacuum tube have longer service life time.
