Abstract
PURPOSE:To perform the adjustment of a stake meter accurately and easily even at relatively low magnification by providing means for deflecting the specimen irradiating electron beam such that it will perform the spinning. CONSTITUTION:The power source 11 for the focusing lens systems IL, PL is adjusted to exchange the signal source for supplying to the deflection coils 12, 13 provided above a specimen 3 from normal deflecting power source 15 to a spinning deflection power source 16 through an interlocked exchange switch 14. When the output signal from said power source 16 is supplied to said coils 12, 13 the spinning deflection is performed where the incident direction angle relative to the optical axis is varied continuously while maintaining the specimen irradiating position and the incident angle of the electron beam for irradiating the specimen 3 constant. Consequently the adjustment of the stake meter can be performed accurately and easily.
