Abstract
The invention is directed at a method and apparatus for auto-focusing an infinity corrected microscope. Light beams are directed and then converged towards a specimen of interest and at least one image is formed from the reflected light. The image, or images, are then reviewed and calibration measurements are retrieved from the image. These calibration measurement are then used to determine focusing measurements which are used to auto-focus the microscope.
