【Abstract】 Pinhol objective lenses with S/D=0.2-1.0 (step = 0.1), D1/D2 = 5,10,20 and Vr/(NI)2= 0.004-0.024 (step = 0.002) are studied. The caussian optical parameters, the spherical aberration coefficients and the chromatic aberration coefficients are calculated. The electron-optical properties of pinhol objective lenses are discussed. These results can provide data for the design of electron microscope.更多还原
