AI Technical Summary
Existing flow cytometers lack precision in adjusting the XYZ dimensions when receiving fluorescence signals, especially in the Z direction where stepless adjustment is not possible, making it difficult to find the optimal position. Furthermore, existing equipment suffers from limited space, high cost, and insufficient accuracy.
The device employs a three-axis adjustment mechanism, including stepless adjustment in the X, Y, and Z directions. Combined with positioning components and a detachable connecting beam, it enables precise adjustment of the fluorescence receiving device. The adjustment mechanism can be removed after finding the optimal position by adjusting the X, Y, and Z directions with a knob, thus saving costs.
It enables rapid and precise adjustment of fluorescence signal reception, avoids displacement or deformation caused by locking uncertainty, reduces equipment cost, and improves the stability and efficiency of optical path signal reception.
