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.

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 Linear 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 provides 2D array including LYSO, CsI(Tl), LSO, GAGG, YSO, CsI(Na), BGO scintillator etc..

Below are kinheng’s typically design drawings for 1D and 2D array for industry.

Relative Light Output Testing For Linear Array

Kinheng has capacity for relative light output comparison testing for LYSO/GAGG with NaI(Tl) by PMT read out.

Uniformity Guarantee

Kinheng will select each single pixel per request, we are able to keep the light output uniformity within ±5%,±10%, ±15% per different requirement. Each slab was carefully selected and tested.
