A reflectron lens for a time-of-flight mass spectrometer is disclosed. The reflectron lens includes a glass tube having a conductive surface along the length of the tube. The conductive surface has an electrical resistance gradient along its length. The electrical resistance gradient provides an electric field interior to the tube that varies in strength along the length of the tube when an electric potential is applied to opposing ends of the tube. A mass spectrometer incorporating the reflectron lens, a method of making the reflectron lens, and an apparatus for removing lead from the surface of a lead silicate glass tube are also disclosed.
