摘要:
An electronic imaging system is disclosed, for assessing the intensity of colorimetric, fluorescent or luminescent signal in a matrix consisting of wells, microwells, hybridization dot blots on membranes, gels, or other specimens. The system includes a very sensitive area CCD detector (18), a fast, telecentric lens (22) with epi-illumination (44), a reflective/transmissive illumination system, an illumination wavelength selection device (34), and a light-tight chamber (24). A computer and image analysis software are used to control the hardware, correct and calibrate the images, and detect and quantify targets within the images.
