Abstract
Devices and systems for reflecting ions are provided. In general, the devices and systems include a plurality of curved lens plates adapted for connection to at least one voltage source and having a passage therein to allow the ions to pass therethrough. The plurality of curved lens plates generates electric fields having elliptic equipotential surfaces that reflect and focus the ions as they pass through the passage. Reflectron time-of-flight (RE-TOF) spectrometers are also provided that include an ion source, ion detector, and such a reflectron as described above. Mass spectrometer systems are provided that comprise an ion source that generates ions and a reflectron TOF spectrometer such as described above.
