MidOpt DB550-850-37.5 Green and 850nm NIR Dual Bandpass Filter

The DB550/850 compliments the DB660/850 and DB475/850 filters. When modifying a single color camera by removing its IR blocking filter, incorporation of this filter in its place allows reflected near-infrared 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). Healthy vegetation will absorb (not reflect) green light and strongly reflect near-infrared light. Thus, this information can then be used to apply a false color gradient to images to highlight better the contrast between regions of healthy vegetation vs. areas with stressed, diseased, or no vegetation.

There is a range of vegetation indices used by the remote sensing and precision agriculture community. While NDVI is probably the most common, each has its advantages. Any indices listed below can be considered when employing a single color sensor camera 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.
