Optical Filters for NDVI Aerial Plant Health Surveys

MidOpt® has designed optical Filters for NDVI. Triple and Dual Bandpass Filters can help go above and beyond traditional Normalized Difference Vegetation Index (NDVI) indicators to modify the way crop health is monitored in order to collect more information than ever before. NDVI was used to determine vegetation health, which utilizes a camera with both a red and (near-infrared) NIR filter, the equation being, NDVI = (NIR – Red) / (NIR + Red).

However, various scientific advances find that modifying this calculation provides more details about crop and farm field health. Like red light, plants also absorb visible blue light, and in addition to the NIR light, healthy plants also reflect some green light.
