A Wien filter is a device consisting of perpendicular electric and magnetic fields that can be used as a velocity filter for charged particles, for example in electron microscopes and spectrometers.[1][2] It is named for Wilhelm Wien who developed it in 1898 for the study of anode rays.[3][4] It can be configured as a charged particle energy analyzer, monochromator, or mass spectrometer.[2][1]
