An optical probe, comprising: a first sleeve (3), a lens (5) being accommodated in the first sleeve, and the first sleeve being provided with a light through hole (31) through which detection light passes; a second sleeve (1), the second sleeve (1) being sheathed with the first sleeve (3) in a movable manner, wherein the second sleeve is provided with a detection window (12) for the detection light which penetrates through the first sleeve and is focused by the lens to be emitted out from the optical probe, and the second sleeve can be moved to a second detection position from a first detection position relative to the first sleeve or moved to the first detection position from the second detection position; and a positioning component (2), the positioning component being used for positioning the second sleeve in the first detection position or the second detection position relative to the first sleeve. The structure can realize the switching between distances from focal points of a lens to a detection window by quickly moving and positioning a first sleeve and a second sleeve, thereby improving the efficiency for an optical probe to detect an object to be detected and an applicable range. |
