    Technical Information

    MidOpt 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. TB550/660/850 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))

    • Useful Range : 543-558nm, 653-668nm, 835-865nm
    • FWHM : 20nm, 20nm, 45nm
    • Tolerance : +/-10nm
    • Peak Transmission : ≥85%
    • Surface Quality : 40/20

     

    Note: Midwest Optical filters are considered to be special order items and are thus not returnable.
