Measurement of twofold astigmatism of probe-forming lens using low-order zone-axis ronchigram

By using a low-order zone-axis ronchigram of a crystalline sample, a simple method for measuring twofold astigmatism of a probe-forming lens is proposed. This method allows precise measurement of the value of astigmatism from only one experimental ronchigram.
