Dark Red Interference Bandpass Filter, 675-692nm - MidOpt Bi685 SWIR such as those in theThe MidOpt Bi685 Dark Red Interference Bandpass Filter is designed for use in aerial vegetative health monitoring applications. The Bi685 isolates the 685nm wavelength range used in some red light vegetative health indices. When plants are stressed or dying, photosynthesis slows down or stops. Infrared (IR) wavelengths are absorbed, while more visible (VIS) light particularly red light is reflected. The Bi685 can also be used with dark red laser
