interference filters

The Interference Filters are narrow frequency-range optical filters for filtering out light of a specific wavelength from a spectrum featuring multiple wavelengths. They can also be used for making a nearly mono-chromatic light source from a continuous spectrum. 

The Interference Filters can be combined with the Component Holder on Stem, enabling it to be used with optical riders and optical benches for a range of demonstrations and experiments related to diffraction.
