HR-512i Details

The SVC HR-512i vis-nir spectroradiometer has all the features of the other i-Series instrument.

Designed for maximum optical performance the SVC HR-512i has:

  • Co-aligned symmetrical and uniform field of view
  • Full conical field of view eliminating spectral discontinuities and step discontinuities at the spectrometer sensor interfaces
  • Conical field of view gives better measurement data for all surfaces, especially heterogeneous surfaces

Sample Scans

Outdoor Reflectance Scan

Outdoor White Panel Radiance


And the HR-512i vis-nir spectroradiometer delivers the highest quality data with industry leading ease of use:

  • Data stored in the built-in computer – no external computer to carry in the field
  • Scene photos and GPS coordinates stored with every file, so you know exactly what the conditions were for each scan
  • Two Bluetooth devices allows the instrument to receive data from an external sensor suite containing up to 16 separate sensors. The sensor suite can include downwelling sensors supplying instantaneous broad or narrow band solar response. The sensor data is stored with the spectral data file, allowing the researcher to understand changes in solar irradiance and assist in corrections
  • Other environmental sensors are available.
