Stray Light Correction Services

Stray Light Correction Services is an algorithm and calibration service from cosine for characterising and correcting spectral stray-light contributions in Earth observation instruments. The service operates at the instrument level, applying spectral point-spread function deconvolution to raw detector data to improve radiometric and spectral accuracy before geophysical retrievals are performed.^[1] cosine has applied the technique to operational EO instruments including TROPOMI-SWIR^[2] and the Metop-3MI imager^[3], with further application to Sentinel-4/UVN reported. The service targets instrument developers, space agencies, and system integrators who require stray-light characterisation during instrument calibration or who need in-orbit correction algorithms embedded in their processing chains.^[1] Whether the service is offered as a standalone commercial contract or exclusively within instrument development programmes has not been confirmed from publicly available sources.^[1]
