Spectral Evolution PSR+ Serie Portable Spectroradiometers: Established, versatile and robust

  • Full-range VIS/NIR (350-(1900)2500 nm) portable spectrometer
  • By using TE-cooled detector arrays in the spectrometer, it has been improved in resolution, speed of operation, and ruggedness which makes it ideal for scientific research
  • Upgraded performance in the SWIR 1 and 2 regions coupled with an improved signal-to-noise ratio for high quality spectra
  • Many accessories for every individual needs (Reference Panels, Contact Probe, PDA, Benchtop Reflectance Probe, Benchtop Illuminator, integrating sphere)

Short Description

The Spectral Evolution PSR(+) series of spectroradiometers provides the best spectral resolution available in a portable, ruggedized spectroradiometer. The new line of field spectroradiometers offers dramatically improved radiometric performance in the SWIR 1 and 2 regions by using advanced TE-cooled detector arrays. The upgraded performance and durability, in combination with low weight and outstanding ruggedness, make the PSR(+) an ideal tool for researchers who need to accomplish higher-quality work in less time than ever before.

Functions

  • DARWin SP Spectral Acquisition Software for data collection, averaging, storage and display of DN, reflectance, radiance or irradiance spectra
  • Ethernet, wireless, PDA and GPS compatibility
  • Internal memory for up to 1000 spectra
  • Data export option for third party software like: SpecMIN, TSG, and GRAMs
