In addition to longitudinal (or axial) chromatic aberration correction, microscope objectives also exhibit another chromatic defect. ... Comatic aberrations are similar to spherical aberrations, but they are only encountered with off-axis objects and are most severe when the microscope is out of alignment.

Geometrical distortion is another artifact often encountered in eyepieces and the zoom lens systems found in stereoscopic microscopes. ... Chromatic Aberration - Chromatic aberrations are wavelength-dependent artifacts that occur because the refractive index of every optical glass formulation varies with wavelength.

In reality, all lenses have chromatic aberration, a property in which different colors of light are focused to different points. When observing a sample through the microscope eyepiece, this defect makes objects appear to have colored edges.
