The tubes detail:
1.The Borosilicate glass agree with ISO***5:***1, with the advantage of higher sunshine darting rate.
2.Collector of a magnetron sputtering coating process.
3. Selective deposition gradual absorption coating, the coating on the sun with a high absorption rate and low emission rate, absorbing than the sun, the hemisphere than the launch, the temperature of air drying
