BP Series Broad Bandwidth
Designed with a broad, Gaussian passband to mimic and accommodate the entire output of the most common LED wavelengths
Test the effects of monochromatic illumination
High transmission ≥90%*
Superior out-of-band blocking
StablEDGE® design reduces angular dependency and minimizes short-shifting effects
Double-side polished glass for exceptional parallelism and optical flatness
Available in sizes up to 165mm sq.
APPLICATIONS: 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
45-55nm FWHM*
Guaranteed peak transmission ≥85%
Superior out-of-band blocking
Designed for use with laser diodes and LEDs in applications with overwhelming ambient light
StablEDGE® design reduces angular dependency and minimizes short-shifting effects
Double-side polished glass for exceptional parallelism and transmitted optical wavefront
Available in sizes up to 165mm sq.
APPLICATIONS: 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
20-35nm FWHM; Narrow bandwidth
High transmission ≥85%
Designed for use with laser diodes
Ideal wavelength separation when multiple light sources of similar wavelengths are present
Reflective, mirror-type surface that helps minimize thermal effects
Available in sizes up to 79.5mm sq.
APPLICATIONS: Bi Series are popular for life science and laser analysis applications where only discrete wavelengths need to be passed to maximize system performance.
