making it an ideal choice for surveillance systems that demand high-quality imaging
The MidOpt Bi808 Near-Infrared (IR) Interference Bandpass Filter can be used to highlight dyes used in labeling
The Bi685 isolates the 685nm wavelength range used in some red light vegetative health indices
this separation makes it possible to post-process the red and blue channels for NDVI by performing the calculation: NDVI = (blue – red) / (blue + red)
featuring 70 Machine Vision Filters for testing in the ultraviolet (UV)
Green Interference Bandpass Filter, 535-558nm - MidOpt Bi550 Neutral Density making it an ideal choiceThe MidOpt Bi550 Green Interference Bandpass Filter is designed to block unwanted ambient light when imaging subjects illuminated with 550nm green LEDs. They are also used to isolate the green vegetation signal used to arrive at EVI (Enhanced Vegetation Index) and other similar plant health numerical indices. MidOpt Bandpass Filters have a broad, Gaussian passband to mimic and accommodate the entire output of the most common LED wavelengths, are
