Notch Filters are used in Raman spectroscopy, confocal or multi-photon microscopy, laser-based fluorescence instrumentation, or other life science applications. Notch Filters are Optical Filters that selectively reject a portion of the spectrum, while tra
What is a Notch Filter (Bandstop Filter)? A notch filter (also known as a bandstop filter or reject filter) is defined as a device that blocks specific frequency while allowing those outside the defined range to pass.
