PRODUCT SUMMARY
KODAK KAF-4320 IMAGE SENSOR
2084 (H) X 2085 (V) FULL FRAME CCD IMAGE SENSOR
DESCRIPTION
The KODAK KAF-4320 Image Sensor is a high
performance monochrome area CCD (charge-coupled
device) image sensor with 2084H x 2085V photoactive
pixels. It is designed for a wide range of image sensing
applications in the 350 nm to 1000 nm wavelength band.
A dynamic range of >32,000:1 is possible with read out
time less than 0.5 seconds.
The sensor is built with a true two-phase CCD technology
employing a transparent gate. This technology simplifies
the support circuits that drive the sensor, reduces the
dark current without compromising charge capacity, and
significantly increases to optical response compared to
traditional front illuminated full frame sensors.
Twenty-four micron pixels are arranged into an array of
2084x2085 photosites. One quarter of the image is read
from each of four outputs. Each output is driven by a low
impedance two stage source follower that provides a
high conversion gain, allowing low noise at pixel rates of
3MHz per output (net readout rate of 12MHz).
