SPECTRAL EVOLUTION is a leading manufacturer of field portable and laboratory 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.

SPECTRAL EVOLUTION 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+)
  • Getac PS-336 PDA provides GPS, photo tagging, a screen that’s made for viewing in direct sunlight, and an almost unlimited capacity for scans
  • Field switchable optics for varying target sizes and measurement modes

All SPECTRAL EVOLUTION 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.

LEAF REFLECTANCE

These scans were generated using DARWin SP Data Acquisition software included with each PSR-Series spectroradiometer. DARWin SP allows users to plot multiple scans on the same graph for easy comparison and analysis. All instruments feature automatic exposure control and auto-shutter for error-free operation.

GEOLOGICAL REMOTE SENSING

The PSR+ can also be used for geological remote sensing and mapping, is supremely reliable in the field and can collect spectra in as little as 100 milliseconds. In this graph, the PSR+ was used to measure reflectance of kaolinite (red), illite (light blue), dickite (green).

PSR-Series of spectroradiometers is ideal for:

Spectral Evolution’s lightweight battery operated portable spectroradiometers can be outfitted with FOV lenses or fiber optics. Units can be handheld, tripod mounted or carried with a shoulder strap or backpack for easy use in the field. We offer fiber optic reflectance probes, leaf clips, and portable computers with wireless bluetooth interfaces to speed up your data collection.
