S7199-01
Front-illuminated FFT-CCDs for X-ray imaging
S7199-01 is a family of FFT-CCD image sensors specifically designed for X-ray imaging. A FOS (Fiber Optic plate with
Scintillator) that converts X-ray into visible-light is mounted on the CCD chip, which enables S7199-01 to acquire the X-ray
imaging. Two CCD chips of symmetric from side to side are mounted closely for realizing the possible minimum dead space in
between. The effective photosensitive length of about 150 mm in total is realized; each chip has 1536 × 128 pixels and the pixel
size is 48 × 48 µm. Even a X-ray image of moving object can be taken by taking a unique operation method of TDI, which can also
be useful for a non-destructive inspection where the object moves on a belt conveyer.
The each chip of S7199-01 has an effective pixel size of 48 × 48 µm and is available in active area of 73.728 (H) × 6.144 (V) mm2.
FOP type is also available (S7199-01F).
