OCR-500
Series
Multispectral Radiometers
The OCR-500 micro-sensor series is a fully digital optical sensor package
that combines precision optics and high performance microelectronics.
Satlantic designed this sensor series for applications where performance,
size and power are key constraints. The OCR-500 series radiometers
can be mounted on real-time profilers, moored, and autonomous
deepwater buoys and autonomous underwater vehicles (AUV’s).
