    Sw-2000m-cl-65 ５ 1 general the jai sweep series sw-2000m-cl-65 is a cmos line scan camera based on a custom-made 2048 pixel imager with large square pixels of 20 µm for high responsivity. It operates at a rate of up to 80,000 scans per second. The camera outputs digital data in 8-, 10-, or 12-bit fo...
