Background
In a detection system of a flow cytometer optical instrument, a plurality of optical elements are generally mounted in accordance with a designed optical path position to achieve a certain optical detection function. However, in practical applications of the optical system, the orientation of the optical path always varies slightly due to dimensional differences of materials, machining precision of optical components, and process tolerance of installation. Therefore, after the preliminary fixing of the optical detection structure is completed, since the pre-installed position cannot completely reach the optimal ideal state, there is always a certain deviation, and the position of the optical element must be finely adjusted during the use. For example, the optical fiber is located at the position where the optical signal is received in the system, and the strength of the received signal can affect the accuracy of the tested output parameter. Data accuracy is achieved only by making moderate adjustments to the position of the signal receiving element to achieve optimal optical coupling.
