Here the pinhole size of a type-II microscope was permitted to vary, and it is shown how the size could affect the imaging properties of a real microscope. The three-dimensional optical transfer function is established, and we discuss in particular the resolution capabilities, lateral as well as longitudinal, of a scanning microscope with a given pinhole size or detector area. Finally, a rigorous confocality criterion, which will answer the question of how small the pinhole should be made to give confocal imaging properties to a scanning microscope, is given.<\/pre>\n<p>&#8220;<em>Dependence of two- and three-dimensional optical transfer functions on pinhole radius in a coherent confocal microscope<\/em>&#8220;, Valter DRAZIC, Journal of the Optical Society of America A, Vol. 9, No 5, May 1992, 725-731<\/p>\n<p>&#8220;<em>Dependence of two- and three-dimensional optical transfer functions on pinhole radius in a coherent confocal microscope &#8211; comments<\/em>&#8220;, C.
