#000000 Bi905 Near-IR Interference Bandpass Filter

Bi905 Near-IR Interference Bandpass filters are recommended for use with 905nm IR diode lasers or diode laser module lighting. 905nm is the wavelength of choice for many manufacturers of autonomous vehicle/driver assistance lidar systems. It is also commonly used in hand-held laser rangefinder applications, laser speed detectors, surveying equipment, cloud ceilometers, proximity fuses, safety curtains, laser therapy devices and weapons simulation. 905nm bandpass filters are therefore often necessary for reducing unwanted noise from sunlight and other ambient light sources, thereby greatly reducing errors by vastly improving signal-to-noise ratios. These single-substrate, hard-coated filters block all UV, visible and near-IR wavelengths outside of the desired 905nm passband.
