Dark Red Interference Bandpass Filter, 675-692nm - MidOpt Bi685 SWIRThe 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
520 nm LEDs are typically used in bioanalytical applications
The MidOpt Ni200 Neutral Density (ND) Filter can be used to reduce the amount of light reaching the camera to an average of 1% transmission
or average 12
The MidOpt Bi808 Near-Infrared (IR) Interference Bandpass Filter can be used to highlight dyes used in labeling
methylene chloride and MEK
This fixed focal lens has a resolution of 170 line pairs per millimeter (lp/mm)
The LP340 is AR coated to limit glare and minimize reflection loss
this filter allows reflected red light (660nm) to be captured in the camera sensor’s red channel and reflected near-IR (NIR) light (850nm) to be captured in the sensor’s blue channel (the green channel is not used)
The MidOpt ND300 Neutral Density (ND) Filter has an optical density of 3
such as those in the blue and violet spectrum
but spectrally different information as compared to traditional NDVI data
making it a great option for harsh
