Bandpass Filters are used in a variety of industries, including machine vision,factory automation, security and surveillance, license plate recognition, medical and life science, agricultural inspection, aerial imaging, motion analysis, photography and cinematography.

BP Series Broad Bandwidth
BP Series are the most popular filters used in machine vision and factory automation systems and are a critical element in fluorescence imaging.

BN Series Narrow Bandwidth
BN Series are popular in outdoor applications where sunlight is present (ex. license plate recognition and security surveillance) and also in fluorescence applications to prevent cross-talk while blocking excitation illumination and ambient light.

Bi Series Narrow Interference Bandwidth
Bi Series are popular for life science and laser analysis applications where only discrete wavelengths need to be passed to maximize system performance.
