Our Advantage:
Minimal pixel dimension available
Reduced optical crosstalk
Good uniformity between pixel to pixel/ Array to array
TiO2/BaSO4/ESR/E60
Pixel Gap: 0.08, 0.1, 0.2, 0.3mm
Performance testing available
2. Kinheng offers various arrays for end application. We can provide CsI(Tl), CsI(Na), CdWO4, LYSO,LSO, YSO, GAGG, BGO scintillation arrays. Based on the application TiO2/BaSO4/ESR/E60 are wildly used as reflective material for pixel isolation. Our mechanical processing keeps the minimal tolerance to optimize array’s physical properties including tolerance, dimension, minimal-cross talk and uniformity etc.

4. Mechanical design for assembling
Based on the end use of assembled array, there are many kinds of mechanic design from Kinheng to meet the medical and security inspection industry.
1D Liner array are mainly used for Security inspection industy, such as Bagger scanner, Aviation scanner, 3D scanner and NDT. Material Including CsI(Tl), GOS:Tb/Pr Film, GAGG:Ce, CdWO4 scintillator etc. They are typically coupled with Silicon Photodiode line array for read out.
2D array are normally used for imaging, including Medical(SPECT, PET, PET-CT, ToF-PET), SEM, Gamma camera. These 2D array are typically coupled with SIPM array, PMT array for read out. Kinheng provide 2D array including LYSO, CsI(Tl), LSO, GAGG, YSO, CsI(Na), BGO scintillator etc.
Below is kinheng’s typically design drawing for 1D And 2D array for industry.
