Spectral Evolution Offers New Spectroradiometer For Irradiance Measurement


Lawrence, Mass.-based Spectral Evolution has released the SR-3501 and SR-1901, laboratory spectrometers for solar irradiance measurement, solar simulator classification and other applications.

These instruments provide 280 nm to 2500 nm and 280 nm to1900 nm capabilities, respectively, the company says. They can provide full-range UV/VIS/NIR/SWIR measurement with one scan and feature autoexposure, autoscaling and auto-dark shutter.

The spectrometers are equipped with the exclusive DARWin SP data analysis software packages, allowing users to validate the spectral match class of any commercially available continuous output solar simulator, per IEC 60904-9/ASTM E927-05, as well as plot data and review results in radiometric or photometric units, the company adds.
