550/660/850nm Triple Bandpass Green+Red+850nm NIR

Triple Bandpass Filter

Description:

This 550/660/850nm triple bandpass filters are primarily designed for aerial agriculture mapping and surveying purposes. Green-Red-Near IR data is used for applications where Chlorophyll Vegetation Index (CVI) and other vegetative index monitoring is preferred. 550/660/850nm filters, when mounted in converted consumer cameras, can help in achieving a more affordable, lightweight alternative to systems using three or more cameras or sensors. Some of the formulas that are employed in these cases include:

Chlorophyll Vegetation Index

CVI = (NIR * Red) / (Green ^ 2)

Normalized Green

NG = Green / (NIR + Red + Green)

Normalized Near Infrared

NNIR = NIR / (NIR + Red + Green)

Normalised Red

NR = Red / (NIR + Red + Green)

Triangular Vegetation Index

TVI =0.5 * (120 * (NIR – Green) – 200 * (Red – Green))
