Notch Filters
Frequently Asked Questions
An optical notch filter is a type of optical filter that selectively blocks a specific wavelength or narrow range of wavelengths while allowing others to pass through.
Optical notch filters are crucial in systems such as spectroscopy, fluorescence microscopy, and telecommunications to eliminate unwanted light or to protect sensitive detectors.
It operates based on interference effects. Thin layers of different materials are constructed so that unwanted wavelengths interfere destructively, blocking them from passing.
They are widely used in Raman spectroscopy to block laser light, in telecommunication systems to filter out specific channels, and in astronomy to observe specific phenomena.
