Abstract
A previously described hot-stage device for high-temperature microscopy, in which specimens are supported by a thermocouple used both for heating and temperature measurement, uses a high-speed switch to interrupt the heating current at intervals during which temperature measurement takes place. Interruption of the heating current by silicon rectifiers minimizes maintenance problems and inaccuracies of temperature measurement which may arise with mechanical switching. Precautions for avoiding other sources of inaccuracy in temperature measurement are also described.Keywords
