SpectraVista Corporation

Focusing on remote sensing applications & manufacturing the instruments that make it possible

Field Portable Spectroradiometers

GER Field Units
Built on over 20 years of research and development, Spectra Vista Corporation instruments combine the leading edge detector technology with precision optics and state of the art electronics to produce the ultimate in field portable spectroradiometers. The versatility of our full line of portable ground spectroradiometers allows measurements in a broad range of areas from ground truthing of airborne campaigns to a number of industrial, military, agricultural, and environmental applications. This spectroradiometric technology enables the user to detemine the nature of the material under analysis without direct contact with the sample.
The configuration for each instrument is described in the table below.
