supply to power an amplifier forming a reference voltage for reference diodes, a first photo cell is provided with a reference light from LED created light directed to the reference. A second LED directs light through the oil mist. The quantity of light is measured by a second photo cell reflecting the light absorbence of the sample, and the output of the two measuring devices is determined in a differential amplifier, driving a meter movement. The direct current signal is at a safe current range for use of the transmitter in a hazardous environment and is inversely proportional to the percent transmission of the signal.
4687337 ATMOSPHERIC AEROSOL EXTINCTIOMETER Harold Stewart, Donald Hansen, Vernon Turner assigned to The United States of America as represented by the Secretary of the Air Force The extinction coefficient of atmospheric aerosol is measured by an instrument in which a single light beam from a graybody source is alternately directed through two similar optical paths to a detector. Each optical path traverses an equal length region of ambient air. Aerosols are filtered from the ambient air region of one optical path .The detector measures the modulation of the incident radiation and its output is a function of the extinction coefficient of the ambient air under test. A second detector is used to monitor the beam power. Processing electronics compute the extinction coefficient of the ambient air under test from the detector outputs. The ambient air regions of the two beam paths are alternately filtered for improved performance.

More particularly, a substrate is exposed to a gas, such as an effluent from a gas plasma, having at least one reactive specie, such as a free radical, the gas having substantially no electrically charged particles present. Simultaneously, the substrate is irradiated with ultraviolet radiation to enhance the reaction rate
