Abstract: The single-pole magnetic lens has been constructed and placed co-axially with the beam of primary electrons below the specimen holder. A scheme of its configuration is shown in Figure 1. The lens had to be designed with consideration to the size of space available in the specimen chamber. The situation was complicated by the necessity of placing a magnet below the specimen holder. For this reason the height of 30 mm and diameter of 55 mm of the magnetic lens were chosen. The dependency of induction B on the current I through the magnet was measured by a T-meter.
