CCD IMAGE SENSOR - ON Semiconductor
Description
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.
