Blue-Orange Shortpass Filter, 425-620nm - MidOpt SP625 Neutral Density traffic control and license plate

traffic control and license plate recognition when there is overwhelming ambient light conditions and is suitable for laser diode and LED illumination

Green Normalized Difference Vegetation Index GNDVI = (NIR – Green) / (NIR + Green)

This fixed focal lens has a resolution of 100 line pairs per millimeter (lp/mm)

this separation makes it possible to post-process the red and blue channels for NDVI by performing the calculation: NDVI = (red – blue) / (red + blue)

Blue-Orange Shortpass Filter, 425-620nm - MidOpt SP625 Neutral Density traffic control and license plateThe 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
