Integrating sphere based spectroradiometer systems

Spectroradiometer systems with integrating sphere for the measurement of UV-VIS-NIR spectral radiant flux (W/nm) and luminous flux (lumens).


Integrating sphere based spectroradiometer systems for measuring spectral flux (W/nm), luminous flux (lumens) and chromaticity metrics. Integrating sphere sizes from compact handheld unit to 1m diameter. 2-Pi and 4-Pi geometry.
