A line of triple bandpass filters for NDVI and ENDVI assess crop health using cameras and unmanned aerial vehicles. The TB550/660/850 covers green, red, and near-infrared (near-IR) wavelengths and the TB475/550/850 covers blue, green, and near-IR. One camera gathers real-time data results at three wavelengths, generating information about plant growth, water usage, soil type, and topography.
