Materion Corporation Narrowband Notch Filter

Customized solutions provide flexible options for our customers. That is why we offer bandpass filters at full width half maximum (FWHM) bandwidth, including options from wideband to ultra-narrowband. For applications requiring an Ultra-Narrow Bandwidth, we can produce bandpass filters for use in the ultraviolet, visible and infrared spectral regions. A bandwidth (FWHM) of one to several angstroms in the visible spectral region is considered “ultra-narrow;” however, there is no strict definition of what constitutes an ultra-narrow bandwidth value for a bandpass filter.
