Compact Field Portable Spectroradiometer

PSR-1100F Spectroradiometers

Small in size– big on performance and features including

  • PSR-1100f has an industry standard FC connection for a range of fiber optic cable lengths and 1,2,3,4,5,8 and 10 degree FOV lenses.
  • Rugged anodized aluminum construction for field reliability.
  • 320-1100nm spectral range.
  • Keypad and function display– can take and store 2500 spectra without a computer.
  • Calibrated for spectral radiance and irradiance with NIST- traceable standards.
  • Tag spectra with GPS, elevation, photo and voice notes with companion GETAC PS336 PDA.
  • High reliability– all photodiode array optics with no moving gratings to break in the field.
  • Auto exposure and auto shutter for easy one-touch operation.
  • Snap-in 2800mAH Li-Ion rechargeable battery for >4 hours of continuous use.
  • Remote sensing with wireless Bluetooth interface.
  • Lightweight– less than 4 pounds.
  • Exclusive DARWin SP Data Acquisition software provided.
