Constituent of a [[time-of-flight mass spectrometer]] that uses a static electric field to reverse the direction of travel of the ions entering it. A reflectron improves [[mass resolution]] by assuring that ions of the same ''[[m/z]]'' but different [[kinetic energy]] arrive at the detector at the same time.

A device used in a time-of-flight mass spectrometer that retards and then reverses ion velocities in order to correct for the flight times of ions having different kinetic energies.  The reflectron is sometimes known as an [[ion mirror]].
