Triple Bandpass Filters from Midwest Optical Systems Inc. are designed for crop health assessment in real time, including information on plant growth, water usage, soil type and topography.
The TB550/660/850 filter takes the traditional red and NIR measurements and adds green. Green/red/NIR wavelengths are used for applications where Chlorophyll Vegetation Index (CVI), Normalized Green (NG) and other vegetative index monitoring is needed.
The TB475/550/850 filter uses blue/green/NIR light instead of the red-based method. It’s recognized as the Enhanced Normalized Difference Vegetation Index (ENDVI), a technique that can provide more detailed information. ENDVI may better isolate plant health indicators and can generate results and false color mapping to indicate values as far down as the pixel level.
