Abstract
Abstract. For spectroradiometers, the characterisation of their
wavelength scale and spectral bandwidth underpins the quality
of measured data substantially. This characterisation can be performed using
metrology-grade tuneable monochromatic sources, which are currently
available only in a few laboratories worldwide. Yet in numerous
applications, only the in-field calibration is a feasible solution. We have
designed and developed a tuneable and portable radiation source (TuPS) in
the wavelength range from 300 to 350 nm for the in-field characterisation
of Dobson spectrometers' wavelength scale and slit function, with standard
uncertainties better than 0.02 nm in wavelength and with the bandwidth of
emitted radiation smaller than 0.13 nm full width at half maximum (FWHM). The TuPS is designed such that only minor modifications of its optical system extend/shift its spectral range towards visible and near-infrared spectral regions and thus expand its
application for characterisation of any spectroradiometers in the relevant
spectral region of interest.
