Bi550 Green Interference Bandpass Filter
Green Interference Bandpass Filter for machine-vision imaging — passes 535-558nm and blocks out-of-band light for repeatable contrast on the line.
Overview [ 01 ]
Bi550 filters are 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.
