RT-MC glass tube
It is developed by the rotary three-target magnetron sputtering technology, having double M-ALN cermet layers. This tube has the advantage of highest thermal efficiency (0.96), lowest emittance rate(ˇÜ0.04/20ˇć) and works effectively in the high temperature(300~500ˇć) in contrast to the normal evacuated tube. The corresponding film structure is ALN/M-ALN(LMVF)/M-ALN(HMVF)/Cu.
