Optical Laboratory Suite
Overview
The world class calibration facilities of the Field Spectroscopy Facility are available to academic and research institutes in the UK and Europe for the calibration of remote sensing field spectroradiometers. These services include the system response calibration of instruments for spectral radiance and irradiance measurements, and the calibration of reference panels for spectral diffuse reflectance measurements. The facility also offers a wavelength validation service for quantifying the spectroradiometer’s wavelength scale errors.
Our laboratory facilities can also be accessed for your own calibration/validation/inter-calibration projects.
Below is a list of some of our available equipment and standards. This list is not exhaustive - please get in contact with us if you have any questions regarding the FSF Laboratory.
