I subscribe to news releases from a variety of places using agriculture as a key word so I’m sure this thing has an agricultural application. This is one of those things you’re never going to hear a radio ad for. Just look at the words in this selection of the release from Analytical Spectral Devices:

Analytical Spectral Devices, Inc. (ASD), the world leader in field portable spectroradiometers announces the release of the new RTS-3ZC Integrating Sphere accessory —a specially designed integrating sphere for use with the ASD FieldSpec® spectroradiometers for accurate reflectance or transmittance measurement of diffuse or scattering materials such as those found in many optical remote sensing, oceanography, forestry and plant physiology applications.

So if you need any “cost-effective, precision, transportable and field-portable, laboratory-quality Vis/NIR spectrometers, spectroradiometers, spectrophotometers and corresponding software and accessories” you know where to get them.
