1. A method for analyzing tissue comprising: obtaining a tissue sample; exposing the tissue sample to one or more different exogenous fluorophores excitable in a range of about 300 nm to about 200 nm and having a useful emission band from about 350 nm to about 900 nm, and including one or more fluorescent dyes or fluorescently labeled molecular probes that accumulate in tissue or cellular components; exciting, with an ultraviolet (UV) light source, the one or more different exogenous fluorophores with a first wavelength of UV light between about 200 nm and about 290 nm; collecting with an optical system, emissions from each of the one or more different exogenous fluorophores at a second wavelength different from the first wavelength of UV light, being from about 350 nm to about 950 nm, and being generated in response to the first wavelength of UV light.
