Spectral Evolution’s UV-Vis-NIR spectrometers and spectroradiometers provide the best combination of high resolution and high sensitivity resulting in the most precise field portable instruments available on the market.
Spectral Evolution’s range of field-portable spectroradiometer bundles set the standard in precision, reliability and portability for spectral radiance, irradiance and reflectance measurements in the range from 350-2500nm. The all-solid-state design has no moving parts and features a silicon array for the UV-VIS-NIR band, with either one or two InGaAs detector arrays for the SWIR band. For the highest sensitivity, the detector arrays are thermoelectrically (TE) cooled.
