UV-Vis-NIR spectrophotometer SphereSpectro 150H

absorptiontransmissionmeasuring

The SphereSpectro 150H is a unique spectrophotometer system for simultaneously discriminating and quantifying both the spectral absorption coefficient and the spectral effective scattering coefficient of scattering media (patented). Different versions are available for the UV, VIS and IR spectral ranges. For clear samples the classical 8°/d measurement geometry can be applied. •Simultaneous determination of: ○Absorption coefficient, µa ○effective scattering coefficient, µs‘ •Measurement on diffuse samples (solid or liquid) •Measurement in classical 8°/d measurement geometry for clear probes (according to DIN 5036-3 as well as CIE-130-1998) •Easy sample handling •Measurement within seconds •Table top device •UV, VIS and IR spectral ranges •Large sample compartment with several probe fixing options •Precise and absolute measurements •Plug & play with intuitive software package The fundamental measurement principle enables the measurement of both parameters, spectral absorption coefficient and spectral effective scattering coefficient. These two parameters are of interest for analyzing diffuse scattering samples based on their physical and chemical properties. Other laboratory measurement devices on the market perform the measurement and analysis based on the absorption or pure transmission only. This is not sufficient when an absolute measurement and more profound and deeper analysis of diffuse scattering samples is needed. Due to a specific algorithm in the software program, the absorption coefficient as well as the scattering coefficient can be determined. This is based on “radiative transport theory”.
