Abstract
A scanning confocal microscope (50) capable of providing ultraviolet (UV) excitation. The optical train substantially corrects scanning and focusing errors over the wavelength range that includes UV and visible wavelengths. In a particular embodiment, the lenses (27, 30') in the common path portion of the optical train are corrected for chromatically induced scanning errors while extra lenses (60, 65) are provided in the forward UV path to correct for focusing errors due to longitudinal chromatic (visible/UV) aberration.
