Full Range Photodiode Array UV-Vis-NIR Spectroradiometer
Working with a spectroradiometer in the lab is necessary for many applications that require handling sensitive materials that cannot maintain their integrity outside of lab conditions, such as calibration transfer or testing solar simulators, and scanning materials that require sanitary conditions. Spectral Evolution offers a variety of spectroradiometers designed with these delicate tasks in mind.
Spectral Evolution’s SR-Series Laboratory spectroradiometers deliver high sensitivity with a high signal-to-noise ratio and an unmatched wide dynamic range. Our spectroradiometers are calibrated for solar radiance to generate a spectral match report for measuring class performance as per IEC60904-9/ASTM E927-05, making them especially useful for measuring continuous or pulse solar simulators.
