HR-768i
The SVC HR-768i provides mid-level spectral resolution field and laboratory measurements covering the 350 nm to 2500 nm spectral region. This is a great option for applications that need a full range instrument but don’t need as high a resolution in the longer wavelengths from 1050-2500 nm. Weighing only 7.9 pounds the HR-768i is one of the lightest full range instruments in the industry.

HR-768i Details
Designed for maximum optical performance the SVC HR-768i has a:
- 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
Features
And the HR-768i delivers high 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 allow 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.
