S8658-01
Front-illuminated FFT-CCD for X-ray imaging
S8658-01 is a FFT-CCD area image sensor specifically developed for X-ray imaging. Since a FOS (Fiber Optic plate with Scintillator) to convert X-
rays into visible light is mounted on the CCD chip, X-ray images can be captured in fine detail. Three CCD chips are linearly arranged in close
proximity to form a long and narrow sensor format. Effective size of each active area is 73.728 (H) × 6.144 (V) mm², so the overall active area
length of the three chips is up to 220 mm in length. Each CCD chip has 1536 × 128 pixels and the pixel size is 48 × 48 µm.
When used in TDI operation mode which is a special feature of this CCD image sensor, even X-ray images of a moving object can be clearly
acquired, making S8658-01 ideal for non-destructive inspection of products carried on a belt conveyor, etc.
