Abstract

The present invention provides an optical system comprising a base plate, an optical assembly and a debugging tool. The optical assembly is connected with the bottom plate, at least one part of the optical assembly is movably arranged relative to the bottom plate, the direction of laser emitted by the optical assembly is a first direction, the direction, perpendicular to the first direction, of the optical assembly on the horizontal plane is a second direction, and the direction, perpendicular to the first direction, of the optical assembly on the vertical plane is a third direction. The debugging tool is connected with the bottom plate, at least one part of the debugging tool is movably arranged relative to the bottom plate, and the debugging tool is detachably connected with the opticalassembly in a split mode and can drive all the components of the optical assembly to move in at least one direction of the first direction, the second direction and the third direction so as to adjustthe relative positions of all the components of the optical assembly. According to the invention, the problems of complex structure and high assembly difficulty of the optical assembly applied to a flow cytometer in the prior art are solved.

Description

technical field [0001] The invention relates to the technical field of medical instruments, in particular to an optical system. Background technique [0002] Traditional flow cytometry has been widely used in blood cell analysis. Such a blood cell analyzer is mainly composed of an illumination unit, a flow chamber, and a signal processing unit. The flow chamber provides an optical detection area, in which the sheath flow principle is used to wrap the blood cell sample flow in the sheath flow, so that the blood cells pass through the detection channel one by one; the light source, usually a laser, provides an illumination beam to irradiate the flow On the detection area of ​​the chamber, when the cells flow through the detection area, the irradiation beam will irradiate the cells to scatter or stimulate fluorescence emission, etc.; the signal processing unit collects various optical information generated in the flow chamber and converts them into electrical signals. After p...
