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

a Bandpass Filter is absolutely necessary

this separation makes it possible to post-process the red and blue channels for NDVI by performing the calculation: NDVI = (red – blue) / (red + blue)

ensuring optimal performance under varied lighting conditions
