Applied Scientific Instrumentation (Eugene, OR) has introduced PhotoTrack, a system specifically designed to solve the problem of tracking a moving specimen. Combined with ASI’s closed-loop DC servo motor stages, PhotoTrack allows users to keep free moving samples in their field-of-view (FOV). PhotoTrack uses a low-light-level rapid position-sensing quadrant PMT sensor to monitor a bright reference spot on the target. It then commands an ASI automated XY stage to maintain that spot in the center of a microscope’s field-of-view.
