BN650 (Discontinued) Narrow Red Bandpass Filter
(Discontinued) Narrow Red Bandpass Filter for machine-vision imaging — passes 638-672nm and blocks out-of-band light for repeatable contrast on the line.
Overview [ 01 ]
DISCONTINUED
BN650 Narrow Red Bandpass filters are useful in applications where intense sunlight or other interfering ambient light is present. BN650 filters are compatible with 650nm laser diodes and LEDs, commonly used in laser pointer and line generators. Compared to traditional interference filters, these filters are less susceptible to short shifting due to angle of incidence variations.
