Abstract
Methods and systems are provided for an auto-focus system for a microscope. In one example, a method for the auto-focus system includes focusing the microscope at a glass-specimen interface of a sample by passing a primary laser beam through a beamsplitting device to generate an additional, secondary laser beam that is a mirror image of the primary laser beam. A location of an objective may be triangulated along a longitudinal axis of the microscope based on a centroid of spectral intensities of each of the primary and secondary laser beams.
