Unlike the normal optical adjusting Mounts, X-Y dimension adjusting components are designed with standard threaded interfaces. The mounted optical components can be directly connected with the X-Y dimension adjusting components.A X-Y dimension adjustment component can be used in different positions in the optical path. The coaxiality of a single component can be independently adjusted, it also can adjust the coaxiality that an optical system composed of multiple components. Standard threaded design, makes it very simple and convenient to replace optical elements.
