Dexela/VAREX/PerkinElmer 2315 CMOS X-ray Detector Repair

[xmjacky]

I have a Dexela 2315 CMOS X-ray Detector, which works normally. Unfortunately, some of the glue between the internal CMOS image sensor and the Fibre Optic Faceplate (FOP) has come off, causing some shadows to be seen at low brightness, as shown in the picture. Does anyone know what kind of glue is used for fixing by the original factory, and whether UV glue can be used for fixing?

thank you
