HyperOCR - Hyperspectral Radiometer

Satlantic designed the Hyperspectral ocean colour radiometer (HyperOCR) sensor series for applications where performance, size and power are key constraints. Our hyperspectral radiometers can be mounted on real-time profilers, moored on autonomous deepwater buoys, autonomous underwater vehicles as well as on ships and airplanes for above-water optic applications.

The HyperOCR optical sensors feature enhanced performance specifications such as increased sensitivity and resolution, providing significant advantages for key applications such as above-water and profiling radiometry. The HyperOCR sensors are fully digital optical packages, providing 136 channels of optical data from 350 to 800 nm.

Features:

• Irradiance and Radiance radiometers for in-water and in-air applications 350 - 800 nm calibrated range
• Fully characterized cosine response Integrated shutter for accurate dark correction Networking capability
• Data logging and processing software included Fast sampling rate (up to 3 Hz)
• Compatible with the Bioshutter anti-biofouling solution
