These filters have traditionally found use in NDVI-type imaging applications. When using a single camera modified for aerial agricultural surveillance, incorporation of these so-called “Superblue” or “Infrablue” filters allows reflected near-infrared light (745-970nm) to be captured in the camera sensor’s red channel and reflected violet light (375-425nm) to be captured in the sensor’s blue channel (the green channel is not used).\u003c\/p\u003e\n\u003cp\u003eEven with an inexpensive consumer camera (that has had its IR-blocking filter removed), this easy separation makes it possible to post-process the red and blue channels for NDVI by performing the calculation: NDVI = (red – blue) \/ (red + blue). Healthy vegetation will absorb (not reflect) blue light and strongly reflect near-infrared light. While “Superblue” filters similar to DB395\/870 have seen much use in recent years, for better wavelength separation and contrast, we strongly recommend our newer DB475\/850 or DB660\/850 dualband filters instead.\u003c\/p\u003e\n\u003cp\u003eAll MidOpt filters can also be purchased unmounted or in custom dimensions upon request from Machine Vision Direct.\u003c\/p\u003e\n\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;
