Abstract: An optical filter 4 is placed in an optical path between a light source unit 1 using a deep ultraviolet LED as a light source and a sample cell 2. The optical filter 4 is a shortpass filter that allows passage of light of a main peak located within a deep ultraviolet region while blocking light of an unwanted peak located within a visible region. The temporal change in the amount of light of the unwanted peak is considerably greater than that of the main peak. The optical filter 4 blocks the former light whose amount considerably changes with time. As a result, the influence of the noise and drift originating from the LED on the detection signal obtained in a detector 3 is dramatically reduced, so that the analytical accuracy is improved.

Abstract: The present invention relates to a photoelectrical feedback sensing system. A first light signal passes through the sensing apparatus. A second light signal corresponding to a characteristic of a sample within the sensing apparatus is outputted from the sensing apparatus. The first photo detector receives the first light signal and outputs a first electric signal corresponding to the intensity of the first light signal. The second photo detector outputs a second electric signal corresponding to the intensity of the second light signal. A driving signal is generated by the micro-processor to drive the light-emitting unit. The micro-processor receives the second electric signal and converts the second electric signal into a digital signal. The feedback circuit modulates the driving signal for maintaining the optical stability of the first light signal so that the sensing system is less affected by environmental temperature fluctuation and noise interferences.

Abstract: An integral, compact infrared reflectance densitometer including a substrate supporting an LED, a control photodiode to compensate for component degradation, a background photodiode to compensate for background radiation, and a large area photodiode to provide an electrical signal representative of the amount of toner particles on the photosensitive surface. Also carried on the substrate is a field lens to focus light rays reflected from the photosensitive surface onto the signal photodiode. The substrate is precisely secured to a molded housing having integral collector and collimating lenses. Four extending pins on the housing engage four apertures on the substrate to locate the substrate with respect to the housing and align the LED and field lens carried on the substrate with the collector and collimating lenses of the housing. Also carried on the substrate is an aperture box to permit a portion of the LED light to project through the collimating lens to the photosensitive surface and a portion of the light to be reflected onto the control photodiode to control light output. The light rays reflected from the photosensitive surface are gathered in a collector lens and projected through the field lens to be focused onto the signal photodiode. An L-shaped clip and an appendage with an elongated aperture extend from opposite ends of the housing to position and align the infrared reflectance densitometer in the reproduction machine with respect to the photosensitive surface.
