Features
The STAR250 sensor is a CMOS Active Pixel Sensor,
designed for application in Optical Inter-Satellite Link beam
trackers. The STAR250 is part of broader range of applications
such as space-borne systems like sun sensing and star
tracking. It features 512 by 512 pixels on a 25
µm pitch, on chip
Fixed Pattern Noise (FPN) correction, a programmable gain
amplifier, and a 10bit ADC. Flexible operating (multiple
windowing, subsampling) is possible by direct addressable X-
and Y- register.
The sensor has an outstanding radiation tolerance that is
observed by using proprietary technology modifications and
design techniques. Two versions of sensors are available,
STAR250 and STAR250BK7. STAR250 has a quartz glass lid
and air in the cavity. The STAR250BK7 has a BK7G18 glass
lid with anti reflective coating. The cavity is filled with N2
increasing the temperature operating range.
Applications
• Satellites
• Spacecraft monitoring
• Nuclear inspection
