GAGG scintillator detector linear photodiode array food inspection
GAGG scintillator detector linear photodiode array food inspection
Kinheng lanuched the GAGG liner detector for X ray imaging industry, we can process Pitch 0.4, 0.78, 1.575, 2.5mm for liner detector, Usually we offer Liner 1x16 elements array for PD coupling. Our testing show GAGG detector is around 3 times better brightness than CdWO4 detectors. The afterglow performance is same as CdWO4 detectors. This is excellent performance for security inspection industry.
