Midwest Optical Systems BN810-25.4 Narrow Near-IR Bandpass M25.4 25.4 C-Mount Narrow Bandpass Filters

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 factory automation applications where overwhelming ambient light (sunlight) may be present and in fluorescence applications to prevent cross-talk, while blocking excitation illumination and ambient light. NIR BN filters are commonly used in outdoor applications such as security surveillance and license plate recognition.
