ABSTRACT:
An apparatus including a plurality of electrodes defining a trapping chamber of an ion trap, wherein at least one of the electrodes is a transparent electrode having at least a portion that is both optically transparent and electrically conductive; a controller connected to the plurality of electrodes, wherein the controller includes a memory containing computer readable instructions which, when executed, cause the controller to send control signals to the plurality of electrodes so that: the plurality of electrodes produce and maintain a trapping field in the trapping chamber, and the plurality of electrodes change the trapping field so that ions of a predetermined mass in the trapping chamber are selectively moved; and an optical detector oriented so that the portion of the transparent electrode that is both optically transparent and electrically conductive is between the optical detector and the trapping chamber.
