STAR-250
Datasheet
Purpose
This document is the data sheet of a Radiation-Hard CMOS active pixel. The
specifications are based upon the results of the electro-optical measurements.
1 Image Sensor Description
The STAR-250/CYIS1SM0250AA sensor is a CMOS Active Pixel Sensor that is
designed for application in Optical Inter-Satellite Link beam trackers. Apart from this,
the design also envisaged a broader range of applications in space-borne systems like sun
sensing and star tracking.
The sensor has an outstanding radiation tolerance that has been obtained by using
proprietary technology modifications and design techniques.
