  • Patent number: 7499154
    Abstract: A readhead for illuminating a sample carrier and receiving light from the sample carrier, including a housing for receiving a sample carrier, an array of light sources mounted within the housing in a fixed position relative to the sample carrier, and including first and second light-emitting diodes for emitting substantially monochromatic light of a two different wavelengths, a light guide mounted in the housing between the light-emitting diodes and the sample carrier, and a light detector coupled to receive light from the sample carrier. The readhead also includes a light source for directing excitation light of a predetermined wavelength to the sample carrier, and a light filter positioned between the sample carrier and the light detector and adapted to prevent passage therethrough of the excitation light. The readhead allows both fluorescence spectroscopy and reflectance spectroscopy to be conducted on the sample carrier.

  • Patent number: 7264971
    Abstract: A readhead for a photometric diagnostic instrument includes a housing adapted for incorporation within the photometric diagnostic instrument, and an elongated sample table operatively engaged with the housing. The sample table is configured to support elongated reagent sample media of the type having a plurality of test areas disposed in spaced relation thereon, each of the test areas being configured to react with a sample and to change color according to an amount of a constituent or property in the sample. A light source is provided to illuminate the sample table. An imager having an elongated field of view is coupled to the housing, the elongated field of view including at least a portion of the sample table. A scanning mechanism is configured to move the field of view relative to the sample table.
