Claim:
1. A microscope comprising: a placement stage having a placement surface for placing an object; a head section, having an optical axis, including a camera configured to acquire an observation image of an object on the placement surface, and a lens coupled to the camera; a first motorized stage lift coupled to the placement stage, and configured to change a vertical position of the placement stage along a first direction orthogonal to the placement surface; a second motorized stage lift coupled to the head section, configured to change a position of the head section along the optical axis of the head section and configured to change an angular position of the head section around a swinging axis orthogonal to the optical axis of the head section so as to perform an inclined observation; and a controller operably coupled to the head section, the first motorized stage lift, and the second motorized stage lift, configured to: for an eucentric positioning, control the second motorized stage lift to change the position of the head section along the optical axis of the head section based on a pre-stored information in response to a user instruction such that a focal position of the head section matches to a height position of the swinging axis where the optical axis of the head section and the first direction orthogonal to the placement surface are in parallel, and control the first motorized stage lift to change the vertical position of the placement stage along the first direction based on the observation image acquired by the camera such that a surface of the object placed on the placement surface is matched to the focal position of the head section where the optical axis of the head section and the first direction orthogonal to the placement surface are in parallel, and the focal position of the head section matches to the height position of the swinging axis, and for a depth synthesis, control the second motorized stage lift to change the position of the head section along the optical axis of the head section to acquire the observation images at different positions of the head section by the camera, and synthesize in-focus pixels of the observation images acquired by the camera to generate a synthesized image.
