MidOpt - FK220 BN Series Filter Kit
The MidOpt FK220 BN Series Filter Kit features popular BN Series Machine Vision Filters for testing in the ultraviolet (UV) and near-infrared (IR). BN Series Filters have reduced bandwidth, which can be beneficial for use with LEDs and laser diodes; overwhelming ambient light conditions, such as outdoor applications; and fluorescence inspection. The filters have 27mm threaded mounts, and step-up and step-down rings are included to fit M25.5 and M30.5 lenses. The FK220 also includes a polarizer filter and film. BN Series Filters are less susceptible to short-shifting with their Stabledge design, reducing angular dependency while maintaining a stable, high-transmission passband.
