The MidOpt LP920 Near-Infrared (IR) Longpass Filter blocks visible (VIS) and unwanted near-IR wavelengths and is designed for use with 940nm LED illumination
ensuring optimal performance under varied lighting conditions
It isolates the wavelength region where the most rapid change in reflectance occurs in foliage
this separation makes it possible to post-process the red and blue channels for NDVI by performing the calculation: NDVI = (red – blue) / (red + blue)
