TDI-CCD area image sensor
S8658-01/01F
Image sensor with a long, narrow photosen-
sitive area for X-ray imaging
The S8658-01 is an front-illuminated FFT-CCD image sensor developed for X-ray imaging. A FOS (Fiber Optic plate with
Scintillator) sensitive to X-rays is directly coupled to the CCD chips, allowing X-ray imaging with high precision. Three CCD
chips are arranged in close proximity to configure a long photosensitive area (approx. 220 mm).
The S8658-01 CCD image sensor features TDI operation that allows capturing clear, sharp X-ray images of objects moving
on a belt conveyor, making it ideal for non-destructive X-ray inspection. FOP type not coated with scintillator material is also
provided (S8658-01F).
