940nm Narrow Bandpass Filter

Description:

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 special applications.

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.
