Bentham’s range of spectroradiometers form part of the measurement suites of many National Measurement Institutions (NMI) and accredited laboratories around the world.

It is acknowledged that such institutions may have very specific requirements, towards which Bentham may provide system components or entire custom system.

An example of such a custom system is here illustrated: for the calibration of UV pyranometers by a national meteorological institute seeking accreditation, has been designed a system that in one setup can perform measurements of cosine response, relative spectral response and absolute calibration.
