GAGG PD Detector High Brightness Low Afterglow
GAGG PD detector high brightness low afterglow
GAGG Ce scintillation crystal has good energy resolution, high light output, high density, no self radiation, no hygroscopic.
Kinheng owns completed process equipment, included line cutting, inner circle cutting, grinding and polished machine, and with our advanced technical capability, we are able to handle complicated and special design from clustomers, like the through hole, reflector coating, matrix design, etc..
Applications: Security inspection (border inspection, package inspection, airport check, etc.), high-energy container inspection, heavy vehicle inspection, NDT, 3D scanning, ore screening and other industrial fields.
