A 564nm bandpass optical filters with a full width at half maximum (FWHM) of 10nm is a type of optical filter that transmits light in a narrow range of wavelengths centered around 564nm, with a width of 10nm at half of the peak transmission value.

This type of filter can be used in various applications where selective filtering of light is required, such as in fluorescence microscopy, spectroscopy, and sensing. For example, if a sample emits light at 564nm, using this filter will allow for the isolation of the signal of interest while minimizing interference from other wavelengths.
