CONFOCAL IMAGING SYSTEM FOR VISIBLE AND ULTRAVIOLET LIGHT

摘要

A scanning confocal microscope (50) capable of providing ultraviolet (UV) excitation. The optical train substantially cor- rects scanning and focusing errors over the wavelength range that includes U V and visible wavelengths. In a particular embodi- ment, the lenses (27, 30') in the common path portion of the optical train a re corrected for chromatically induced scanning errors while extra lenses (60, 65) are provided in the forward UV path to correct f or focusing errors due to longitudinal chromatic (visi- ble/UV) aberration.
