TB475/550/850 Triple Bandpass Blue+Green+850nm NIR Filter, when mounted in converted consumer cameras used in aerial surveying applications, can help provide a more affordable, lightweight alternative vs. systems employing three or more cameras or sensors. Blue-Green-Near IR Extended Normalized Difference Vegetation Index (ENDVI) data gathered for vegetative health monitoring can be used to provide similar, but spectrally different information as compared to traditional NDVI data. Soil background, differing atmospheric conditions and various types of vegetation can all influence the reflection of visible light somewhat differently. ENDVI analysis may, at times, be able to impart more accurate or reliable information regarding plant or crop health by additional leveraging of information in the blue portion of the spectrum. The formula used is:

ENDVI = [(NIR + Green) – (2 * Blue)] / [(NIR + Green) + (2 * Blue)]

  • Useful Range : 468-483nm, 543-558nm, 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.
