Fabry-Perot Filters
This type of filter transmits a narrow band of wavelengths and rejects wavelengths outside of that band. An interesting feature of this type of filter is its ability to “select” a different peak wavelength as the filter is tilted. The movie shown below illustrates how a wavelength from 500 to 550 nm can be selected as the filter is tilted from 60 to 0 degrees.
