Abstract

An imaging system for obtaining images of a specimen that includes a novel filtering system for filtering radiation emitted from the specimen. The imaging system includes a camera and a novel filter grid that is controllably movable relative to the camera in a manner to move a selected emission filter of a plurality of emission filters carried by the grid into position between the camera and the specimen. The filter carrying grid of the system resides in a plane having X and Y coordinates and the system includes a novel positioning mechanism for controllably moving the filter carrying grid along the X and Y coordinates of the plane in a manner to position a selected one of the emission filters carried by the grid into position between the camera and the specimen.
