BP845 Near-IR Bandpass Filter

BP845 bandpass filters are designed to provide excellent transmission at 850nm while blocking visible and lower near-IR wavelength transmission. At the same time, it will block longer wavelength near-IR light – particularly at 940nm. In covert or other near-IR applications where more than one near-IR light source is desired (typically 850nm and 940nm would be two common choices), BP845 can be used with cameras and lighting designed to capture 850nm images and will block unwanted/interfering 940nm illumination.

BP845 Transmission Data

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.
