Summary Specification

KAI-4021 Image Sensor

DESCRIPTION

The KAI-4021 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 μm

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.
