Devices, systems and methods are described that can be used to develop confocal microscopes with high lateral resolution. One example confocal microscope includes a first dispersion element that receives a light beam and to produce illumination beams with different spectral components, and an objective that receives reflected light upon reflection of the illumination beams from a target. The confocal microscope further includes a second dispersion element that receives the reflected light after propagation through in the objective lens, and a third dispersion element that receives the dispersed light associated with the second dispersion element and provides an output light to a camera lens for focusing onto a detector. The second and the third dispersion elements are positioned such that each point on the detector is conjugate to a corresponding single point on the target. Some applications of the disclosed confocal microscopes include skin disease diagnosis and imaging of freshly-excised tissues.
