Abstract

A microscopy system and method of focusing the same are disclosed herein. The microscopy system may include an objective, and imaging device, an illumination source, an epi-illumination module, and a controller. The imaging device is configured to capture a single image of a specimen positioned on a stage of the microscopy system. The illumination source is configured to illuminate the specimen positioned on the stage. The epi-illumination module includes a focusing mechanism in a first primary optical path of a light generated by the illumination source. The focusing mechanism is tilted in relation to a plane perpendicular to the first primary optical path. The controller is in communication with the illumination source. The controller is configured to focus the microscopy system based on a pattern produced by the focusing mechanism on the single image captured by the imaging device.
