Abstract

In a comment on resolution in light microscopy1, Stelzer makes some misleading, if not erroneous, points. His claim to have himself demonstrated the relationship between Abbe's diffraction limit and Heisenberg's uncertainty principle is surprising: this relationship is readily derived from the Fourier theory. The resolution criterion that he seeks to convey is more perplexing: in his description of Dyba and Hell's work2, Stelzer ignores the fact that the resolution of any recording system, whether optical or of any other type, is determined by the span of signal frequencies transferred. The higher the transferred frequencies, the finer are the details and the better is the resolution.
