A 700nm bandpass filter with a Full Width at Half Maximum (FWHM) of 10nm selectively permits light within a narrow range of wavelengths centered around 700nm to pass through efficiently. The FWHM value of 10nm indicates that the filter has relatively high spectral resolution, enabling transmission of light within approximately a 10nm range around the central wavelength of 700nm.

Bandpass filters of this specification are employed in various applications like astronomy, remote sensing, and medical imaging, where precise control over specific wavelengths of light is crucial for data acquisition, analysis, or visualization.
