Back-illuminated photodiode arrays for X-ray
non-destructive inspection
The S11212 series 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 prod-
uct (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
S11212 series can replace the S5668 series since their package size and pin connections are identical.

* This photodiode array as it is does not function as an X-ray detector.
An appropriate scintillator or phosphor sheet should be added at user’s side.
Application example
General photometry
X-ray non-destructive inspection of slow-moving
objects (baggage inspection, etc.)
X-ray non-destructive inspection of fast-moving
objects (baggage inspection, etc.)
X-ray non-destructive inspection (at low X-ray
energy)
Precautions
CsI(TI) scintillator of the S11212-121 has deliquescence. Avoid storing or using the S11212-121 at high humidity.
