NDVI Blue 446nm + NIR 800nm

This is a high quality dual-band NDVI filter with superior contrast between the bands and no spectral cross-talk. This filter easily lets you see where vegetation is thriving and is not. Please make sure you use with a lens that DOES NOT have an Infrared (IR) Cut - Visible Light Filter so that you can capture the infrared light.



Plants absorb visible light and reflect infrared light. By dividing the red channel (Near Infrared Light) by the blue channel (Visible Light) of images captured using this filter the resulting gray-scale image can have a false-color "heat-map" gradient applied to it.

Supermount Version:
This small filter is inserted into the sensor side of the Supermount during internal GoPro Supermount installation. Simply push the filter in with a clean cloth or non-marring tool making sure both sides are free of dust and smudges.
