Compact digital fluorescence microscope

The invention discloses a compact digital fluorescence microscope, which comprises a microscope main body, a sample fixing frame, a fluorescence light source, an objective lens, a fluorescence turntable, a reflective mirror and a camera, a focusing mechanism for adjusting the focal length of the objective lens is arranged on the lens main body; the focusing mechanism comprises a focusing nut rotationally mounted on the lens main body, and a transmission assembly which is in transmission connection with the focusing nut and drives the objective lens to vertically move along the gravity line direction along with the rotation of the focusing nut; the elastic assembly is elastically arranged between the transmission assembly and the telescope body main body, and the elastic force of the elastic assembly drives the transmission assembly to move downwards in the gravity line direction. According to the fluorescence microscope, a traditional binocular observation mirror is omitted, and the size is smaller; moreover,
