The MidOpt Bi350 Near-Ultraviolet (UV) Interference Bandpass Filter can be used with 350nm UV LED
with minimal effect on the red portion of the spectrum
this separation makes it possible to post-process the red and blue channels for NDVI by performing the calculation: NDVI = (red – blue) / (red + blue)
or average 12
This fixed focal lens has a resolution of 100 line pairs per millimeter (lp/mm)
Blue-Orange Shortpass Filter, 425-620nm - MidOpt SP625 Neutral Density The MidOpt Bi350 Near-Ultraviolet (UV)The MidOpt SP625 Blue Orange Shortpass Filter is used to remove most of the red wavelengths and all of the near infrared (IR) light. Some camera sensors may have an overwhelming amount of red, affecting the color of the image; if this is the case, the SP625 may be a better option. MidOpt Shortpass Filters have a broad, Gaussian passband to mimic and accommodate the entire output of the most common LED wavelengths and are anti reflection (AR) coated to
