Description

The MidOpt DB660_850-48 has been designed primarily for NDVI imaging applications. When using a single camera, incorporating this filter allows reflected red light (660nm) to be captured in the camera’s red channel and reflected near-infrared light (850nm) to be captured in the blue channel (the green channel is not used).

Even with an inexpensive consumer camera (which 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 = (blue – red) / (blue + red). Healthy vegetation will absorb (not reflect) red 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.

All MidOpt filters can also be purchased unmounted or in custom dimensions upon request from Machine Vision Direct.
