940nm Narrow Bandpass Filter
Bandpass filters transmit light only within a defined spectral band
ranging from less than one to many nanometers wide. They are used
in a wide variety of applications where spectral isolation is
required. Bandpass filters are preferable to monochromators because
of their higher transmission and better signal-to-noise.
Standard or customized features with different functions for the
940nm Narrow Bandpass Filter compatibly used with 940nm LED light
or laser light source, which the image sensor only requires a small
bandwidth of the 940nm NIR light to for the black and white image.
