16-element Si photodiode array
The S11299-421 is a back-illuminated type 16-element photodiode array specifically designed for non-destructive X-ray inspection. It has improved sensitivity uniformity and smaller photodiode element variations compared to our previous product (S5668 series). The back-illuminated photodiode array is also simple to handle and easily couples to scintillators without having to worry about wire damage because there are no bonding wires and photosensitive areas on the back side. The S11299 series is compatible with dual energy imaging bacause it can be used in combination with our S11212 series [board size: 25.4(W) × 20.0 (H) mm] to configure an upper and lower two layer structure capable of simultaneous detection of high and low X-rays.
