KAF-18500
5270 (H) x 3516 (V) Full
Frame CCD Image Sensor
Description
The KAF−18500 is a dual output, high performance color CCD
(charge coupled device) image sensor with 5270 (H) x 3516 (V)
photoactive pixels designed for a wide range of color image sensing
applications including digital imaging. Each pixel contains
anti−blooming protection by means of a lateral overflow drain thereby
preventing image corruption during high light level conditions. Each
of the 6.8 mm square pixels are selectively covered with red, green or
blue pigmented filters for color separation. Microlenses are added for
improved sensitivity.
The sensor utilizes the TRUESENSE Transparent Gate Electrode to
improve sensitivity compared to the use of a standard front side
illuminated polysilicon electrode.
