405nm Optical Bandpass Filter with FWHM 25nm

A 405nm optical bandpass filter with a Full Width at Half Maximum (FWHM) of 25nm is a precision optical component designed to transmit light around the center wavelength of 405nm while effectively blocking or attenuating light outside of the specified spectral range. This type of filter provides a balance between broad transmission and robust blocking characteristics, making it suitable for a variety of applications that require wavelength-specific filtering.
