  • Analysis of samples by electrophoresis using a charge coupled device
    Patent number: 4874492
    Abstract: Light from the pattern of spots of bands resulting from electrophoresis is detected by a two-dimensional charge coupled device, visualization of the spots or band being achieved by irradiating the gel with a U/V source to stimulate fluorescent markers preferably applied before running of the gel. The charge coupled device is cooled to suppress thermal dark current and, more particularly, to improve sensitivity and dynamic range.

  • Imaging of light-opaque specimens by transmission of radiation therethrough
    Patent number: 4852137
    Abstract: A method of and apparatus for imaging light opaque specimens wherein a secondary source (16) is stimulated by radiation (x-rays or high energy electrons or neutrons) transmitted through the specimen (12) and visible light emitted by the secondary source (without amplification) is detected by a cooled slow scan CCD (26, 28) coupled to the secondary source by a lens (20) and shutter (22).
