The SR9910-V7 computer controlled spectroradiometer is designed for the measurement of spectral irradiance and radiance in the ultra-violet, visible and near infra-red spectra. Using flexible fibre light guides and a range of optical accessories, many optical measurements are made possible, including chromaticity coordinates, total or diffuse reflectance and transmittance. Specialised software provides user friendly control of the instrument with data storage, mathematical analysis and graphing.
The first double monochromator spectroradiometer was produced in 1990 to meet the growing requirement to measure ultra violet radiation and in particular the UVB content of sunlight and artificial sources.
Since then the SR9910 spectroradiometer has be enhanced to it's latest version, V7 where it now boasts a small light weight package, a TEC cooled PMT detector and parallel monitoring with an external detector. The latter now enables the measurement data to be compensated during a scan to reduce the effect of constantly changing sources.
Applications include measurements on LEDs, fluorescent sources and visible and near infra red spectral irradiance.
