Abstract
A microscopic image detecting instrument includes a microscope, a photographing device, a driver, a mark having a predetermined distance from an object, and a controller coupled to the photographing device and the driver. The microscope includes an object stage for holding the object and an objective lens for focusing on and magnifying the object. The photographing device is set above the objective lens to photograph an image presented by the objective lens. The controller controls the driver to move at least one of the object stage and the objective lens to an actual focusing position, according to an actual focal length to the object. The actual focal length to the object is calculated by the controller according to a comparison between an optical definition of a mark image taken as a preliminary target of focus against a predetermined definition calibration curve and the distance between the mark and the object.
