Description
The Kodak KAI-4020 Image Sensor is a high-
performance 4-million pixel sensor designed for a
wide range of medical, scientific and machine vision
applications. The 7.4
m square pixels with
microlenses provide high sensitivity and the large full
well capacity results in high dynamic range. The two
high-speed outputs and binning capabilities allow for
16-50 frames per second (fps) video rate for the
progressively scanned images. The vertical overflow
drain structure provides antiblooming protection and
enables electronic shuttering for precise exposure
control. Other features include low dark current,
negligible lag and low smear.
All parameters above are specified at T = 40*C
