A 415nm bandpass optical filters with a full width at half maximum (FWHM) of 25nm is designed to allow only a narrow range of wavelengths around 415nm to pass through the filter, while blocking other wavelengths. This filter can be useful in a variety of applications, such as:Fluorescence microscopy, Spectroscopy, Photography, Industrial manufacturing
