Claim:
1. A method of providing a chemical analysis of a manufacturing surface, comprising: (a) supplying a manufacturing surface to be analyzed; (b) applying ultraviolet excitation radiation from a source directly or indirectly onto the manufacturing surface to produce fluorescence emission radiation within a first range of wavelengths; (c) receiving the emission radiation, directly or indirectly, from the manufacturing surface at at least one first spectral filter which is capable of passing the emission radiation within at least a portion of the first range of wavelengths along at least one first optical path; (d) measuring an amount of the fluorescence emission radiation using at least one first detector located directly or indirectly along the at least one first optical path; and (e) correlating information concerning the amounts of the fluorescence emission radiation from the measuring by the at least one first detector with data associated with one or more chemical compounds of interest to provide at least a partial chemical analysis of the manufacturing surface, wherein the source comprises a source selected from the group consisting of: (1) a semiconductor source, (2) a an electron beam pumped semiconductor laser; (3) an electron beam pumped incoherent semiconductor source; and (4) an electron beam pumped AlGaN source; and (5) a hollow cathode laser.
