a radiometer that is capable of measuring spectral radiometric quantities directly, such as spectral irradiance or spectral radiance
A device which measures the energy reflected or radiated by materials in narrow electromagnetic wavebands.
an instrument designed to measure spectral irradiance. Spectroradiometers gathered the data in NREL's Solar Spectral Radiation Data Base.
A device that measures the amount of reflected or radiated energy from a surface in two or more wavelengths.
A device for measuring the spectral radiance of a display. To calculate NVIS radiance, MIL-L-85762A requires a scan from 450 to 930 nm, the response range of unfiltered Gen 3 NVIS.
Spectroradiometers, (aka - spectraradiometer) which operate almost like the visible region spectrophotometers are designed to measure the spectral power distributions of illuminants in order to evaluate and categorize lighting for sales by the manufacturer or for the customers to confirm the lamp they decided to purchase is within their specifications.
