MidOpt BN Series Filter BN520
Uniforce Product
Salient Features
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.
BN Series Narrow Bandwidth
- Useful Range : 510-545nm
- FWHM* 55 nm
- Tolerance : +/- 7nm
- Peak Transmission : ≥85%
- Surface Quality : 40/20
- StablEDGE® design reduces angular dependency and minimizes short-shifting effects
- Double-side polished glass for exceptional parallelism and transmitted optical wavefront
BN Series Narrow Bandwidth
MidOpt StablEDGE™ optical filters are specifically designed to be less susceptible to effects from angular shifting seen when optical filters are placed in front of short focal length (<12 mm) camera lenses.
StablEDGE™ filters take advantage of absorptive filter glass to form the leading
edge of the filter passband.This assures no shifting in this region, even when the
lens FOV exceeds 100°.StablEDGE™ designs are less angle-of-incidence sensitive, inherently more rugged, and are environmentally stable.
