When modifying a single color camera by removing its IR blocking filter, the 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 be used to apply a false-color gradient to images, better highlighting the contrast between healthy vegetation and areas with stressed, diseased, or no vegetation.\u003cbr\u003e\u003cbr\u003eThere is a range of vegetation indices used by the remote sensing and precision agriculture community, and while NDVI is probably the most common, each have their advantages. Any of the indices listed below can be used when employing a single-color sensor camera that has been converted with a DB550\/850 filter. Information gathered can then be overlaid on vegetation maps to inform better crop management decisions.\u003cbr\u003e\u003cbr\u003eGreen Chlorophyll Index\u003cbr\u003eCIg = (NIR \/ Green) – 1\u003cbr\u003e\u003cbr\u003eGreen Difference Vegetation Index\u003cbr\u003eGDVI = NIR – Green\u003cbr\u003e\u003cbr\u003eGreen Normalised Difference Vegetation Index\u003cbr\u003eGNDVI = (NIR – Green) \/ (NIR + Green)\u003cbr\u003e\u003cbr\u003eGreen Ratio Vegetation Index\u003cbr\u003eGRVI = NIR \/ Green\u003cbr\u003e\u003cbr\u003eGreen Soil Adjusted Vegetation Index\u003cbr\u003eGSAVI = [(NIR – Green) \/ (NIR + Green + 0.5)] * (1 + 0.5) \u003cbr\u003e\u003cbr\u003eAll MidOpt filters can also be purchased unmounted or in custom dimensions upon request from Machine Vision Direct.\u003c\/p\u003e\u003c\/div\u003e\u003c\/div\u003e\u003c\/div\u003e\u003cdiv style=\"margin-top: 20px;\"\u003e\n\u003ch3 class=\"card__title heading h3\"\u003eTechnical Specifications\u003c\/h3\u003e\n    \u003cdiv class=\"collapsible-section\" style=\"margin: 20px 0;
