Dual Bandpass Blue + 850nm Near-Infrared (IR) Filter - MidOpt DB475/850 Size:30.5mm The attachment fitting easily screws

The attachment fitting easily screws into the 1/4-20 camera thread found on most handheld viewers

These filters are also excellent for use in vegetative health monitoring applications where separate blue plus near-IR imaging sensors / cameras are used as opposed to the more traditional NDVI index applications that utilize red plus near-IR wavelengths

Dual Bandpass Blue + 850nm Near-Infrared (IR) Filter - MidOpt DB475/850 Size:30.5mm The attachment fitting easily screwsThe MidOpt DB475 850 Dual Bandpass Blue + 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 sensors red channel and reflected blue light (475nm) to be captured in the sensors blue channel (the green channel is not used). Even when using an inexpensive consumer camera (that
