Abstract: A fluorescence dot area meter for accurately measuring halftone dot area on a printing plate having an emulsion containing one or more fluorescent compounds. The fluorescent dot area meter generally includes an illumination source for providing light having a first range of wavelengths, a system for exposing the printing plate to this light to cause the printing plate to emit light (fluoresce) within a second, higher range of wavelengths, and a system for determining halftone dot area based on a measurement of the light emitted by the printing plate.

Abstract: An apparatus for detecting the presence of polycyclic aromatic hydrocarbons in the effluent of a turbulent commercial combustion system for monitoring or controlling the composition of the effluent. The apparatus is a system for directyl selectively detecting the presence in the effluent high molecular weight polycyclic aromatic compounds having five or more rings by laser induced fluorescence. The system includes an illuminating source of select fluorescence excitation of wavelengths that induces substantial fluorescence by high molecular weight polycyclic aromatic hydrocarbons in the gas phase. Sampling structure is constructed to provide optical access to the effluent stream to sample the effluent stream at a select position where high molecular weight polycyclic aromatic compounds having five or more rings may be present in sufficient amounts that the fluorescence from the effluent at the select position at the excitation wavelength is predominantly from high molecular weight polycyclic aromatic compounds having five or more rings, when the high molecular weight polycyclic aromatic compounds are present in sufficient amounts. A detector detects the fluorescent signal from the illuminated effluent and an analyzer analyzes the signal to directly selectively determine the presence of the high molecular weight polycyclic aromatic hydrocarbons having five or more rings in the effluent.

Abstract: A light intensity modulator with a predefined range of modulation wavelengths (preferably a narrow range) can be adjusted by a control signal. This modulator receives a light beam and retransmits a modulated light beam in which any wavelength within the modulation range is modulated. A light intensity detector receives this modulated beam and outputs an electrical signal which is a function of the luminous intensity detected. Such a device finds particular application as a spectrophotometer.

Abstract: An apparatus and method for determining the time at which a plasma etching process should be terminated. The process generates at least one etch product species and a continuum plasma emission. The apparatus monitors the optical emission intensity of the plasma in a narrow band centered about a predetermined spectral line and generates a first signal indicative of the spectral intensity of the etch product species. The apparatus further monitors the optical emission intensity of the plasma in a wide band and generates a second signal indicative of the spectral intensity of the continuum plasma emission. The apparatus further monitors the magnitudes of the first and second signals and generates a termination signal when the magnitudes diverge.

Abstract: A conversion assembly for converting a spectrophotometer to a fluorometer which utilizes the light source and light detector of the spectrophotometer. The assembly has a conversion adaptor which is positionable in the spectrophotometer between the light source and the light detector. The adaptor is an enclosure having a receptacle for holding a sample container filled with the sample being analyzed and having openings formed therein to provide a light path for excitation light from the light source to the sample container and further to provide a light path for emitted luminescent light from the sample container to the light detector. In one embodiment the excitation light is centered on an optical shield on the front of the enclosure while light receiving openings at the edges of the front of the enclosure are positioned to receive off center excitation light. In another embodiment a light receiving opening is formed in the side of the enclosure and excitation light centered on the front of the enclosure is reflected around to the opening in the side of the enclosure by a plurality of reflectors.

Abstract: A method of optically detecting a change in intensity of an emission peak in a plasma process, such as a plasma etching process, by reflecting an emission spectrum of radiation from the plasma reaction off of a pair of rugate filters. The reflected emission spectrum has increased in-band reflections and decreased out-of-band reflections which provides reduced noise and an easier-to-detect emission peak. The method can be used for end-point detection in a plasma etching process such as etching of SiO.sub.2.
