SPECTRAL EVOLUTION Field Portable Handheld Spectrometers &
Spectroradiometers are lightweight, battery operated and easy
to move from project to project- perfect companion for many
applications including mineral reflectance, vegetative studies,
solar analysis and ground truthing of airborne hyperspectral
Our field portable, remote sensing units offer all of the advanced
features of our lab units including:

  • 100% linear photodiode array platform- with InGaAs and
    silicon detectors for best resolution and sensitivity @ 350-
    2500nm ranges
  • Fast, full spectrum UV-VIS-NIR measurements with one-
    touch operation- autoexposure & auto dark current shutter
  • Diffraction grating / beam splitter optics- no moving
    gratings or trifurcated fiber optics to break in the field
  • No internal fiber optics- allows maximum sensitivity and S/N
    ratio with higher performance direct FOV lens optics
  • Industry standard optional SMA fiber optic connection for
    easy interchangeability
  • Lightweight (<7 lbs with slide-in LiIon rechargeable battery)
    and easy to carry

SPECTRAL EVOLUTION PSM Series Spectrometers use firmly attached diffraction grating-based internal optics with multiple photodiode array detectors. This ensures both high sensitivity and resolution without having to use light-robbing internal fiber optics, ultra-narrow slits or moving gratings & prisms that can get knocked out of alignment. PSM-Series Spectrometers can collect spectra in as little as 100 milliseconds. The exclusive DARWin SP Data Acquisition Module included with each unit allows for full featured instrument control and data handling and is compatible with UNSCRAMBLER for further data manipulation. LABVIEW drivers are also available (please inquire). In the graph above, the PSM-3500 was used to measure reflectance of kaolinite (purple), illite (green), montmorillonite (red) and SRM-1920 (cyan). The DARWin SP Data Acquisition Module allows multiple scans to be charted simultaneously for easy data analysis
