= Atomic line filter
{wiki=Atomic_line_filter}
An atomic line filter (ALF) is a device used in spectroscopic applications to isolate specific wavelengths of light corresponding to the absorption or emission lines of particular atoms. These filters exploit the unique atomic spectra of elements, which consist of discrete lines representing the energy transitions between different electron states in an atom. \#\#\# Key Features of Atomic Line Filters: 1. **Selective Wavelength Isolation**: Atomic line filters allow for the transmission of light at specific wavelengths while blocking other wavelengths.
