Rayleigh resolution equation
Webforgotten. While equation (6) would apply to any small pattern of lines and spaces (that is, any pitch applied to equation (2) so that only the zero and first orders go through the lens), Lord Rayleigh essentially looked at the extreme case of the smallest pitch that could be imaged – the resolution limit.
