Dual Bandpass
higher peak transmission and superior blocking of UV and near-infrared (IR) wavelengths compared to commonly found all-dichroic green bandpass filters – improving contrast by blocking significantly more of the unwanted light
940nm LEDs don't emit the faint red glow associated with 850nm and other lower near-IR (NIR) LED wavelengths
The MidOpt DB475/850 Dual Bandpass Blue + 850nm Near-Infrared (IR) Filter is designed for Normalized Difference Vegetation Index (NDVI) imaging applications
it will not vibrate during use or be accidentally moved during cleaning
