Abstract:A straightforward and transparent model, based on Gaussian beam optics, for the axial r0 resolution of a confocal microscope is presented. A confocal Raman microscope was used to determine the axial confocality in practice. The axial response of a thin planar object was measured for three different objectives, two pinhole sizes and a slit. The results show that, in the case of a confocal configuration, the response calculated with the model provides a good prediction of the axial resolution of the confocal microscope.
