SPECTRAL EVOLUTION is a leading manufacturer of field-portable and laboratory NIR spectroradiometers and spectrometers for remote sensing applications including geological remote sensing, ground-truthing, spectral remote sensing, environmental and climate research, crop and soil research, vegetative studies, forestry and canopy studies, radiometric calibration transfer, upwelling and downwelling measurement and more. Our 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 NIR spectroradiometers provide:

• Fast, full-spectrum UV-VIS-NIR measurements - 350-2500 nm with just one scan

• Superior reliability in the field with 100% diode array optics with no moving parts

• Bluetooth interface - ditch the rats nest of cables

• Lithium-ion rechargeable batteries for field use

• Lightweight and rugged

• Standalone operation - internal memory holds 1000 scans (PSR+)

• ALGIZ 8X rugged handheld tablet for field use running DARWin LT on Windows 10 with digital camera, and GPS

• Field switchable optics for varying target sizes and measurement modes

All SPECTRAL EVOLUTION NIR spectroradiometers include our exclusive DARWin SP Data Acquisition and Analysis software for one-touch, full range spectroscopic analysis of samples. DARWin SP automatically saves data as ASCII files for use with 3rd party software without post-processing.

SPECTRAL EVOLUTION NIR spectroradiometers feature NIST- traceable calibration for spectral radiance & irradiance measurements:
