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.
Contact us today and ask us about our portable
case options and custom accessories!
If you are using remote sensing for forest health, monitoring
climate change, developing satellite calibrations, mineral
identification and classification, antiquities restoration, urban
development tracking, botanical studies, or water body studies,
then SPECTRAL EVOLUTION can provide a range of field portable
With our instruments, you can apply hyperspectral
spectroradiometers to your research in the field, without lugging
around a heavy instrument backpack with a tangle of cables.

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
  • 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 agricultural 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.

The graph above shows reflectance spectra that were collected from green and
fiber optic illumination module, fitted with an optional 1.2meter bifurcated fiber
optic cable. The 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.
