The MidOpt DB550/850 Dual Bandpass Green + 850nm Near-Infrared (IR) Filter is designed for Normalized Difference Vegetation Index (NDVI) imaging applications. When using a single camera, this filter allows reflected near-IR (NIR) light (850nm) to be captured in the camera sensor's red channel and reflected green light (550nm) to be captured in the sensor's green channel (the blue channel is not used). This information can then be used to apply a false color gradient to images to better highlight the contrast between regions of healthy vegetation versus areas with stressed, diseased or no vegetation. MidOpt Multi-Bandpass Filters have a broad, Gaussian passband to mimic and accommodate the entire output of the most common LED wavelengths, are double-side polished for exceptional parallelism and optical flatness and are anti-reflection (AR) coated to limit glare and minimize reflection loss.

There are a range of vegetation indices used in agriculture. Normalized Difference Vegetation Index (NDVI) is most common, but each have their advantages. Any of the indices listed below can be considered when employing a single color sensor camera that has been converted using a DB550/850 filter. Information gathered can then be overlaid on vegetation maps to provide information used to make better crop management decisions.

Green Chlorophyll Index CIg = (NIR / Green) – 1

Green Difference Vegetation Index GDVI = NIR – Green

Green Normalized Difference Vegetation Index GNDVI = (NIR – Green) / (NIR + Green)

Green Ratio Vegetation Index GRVI = NIR / Green

Green Soil Adjusted Vegetation Index GSAVI = [(NIR – Green) / (NIR + Green + 0.5)] * (1 + 0.5)
