Large optical systems, such as telescopes in satellite laser ranging systems, require precise alignment to realize their optical design. Proper alignment is essential for these systems to function properly. While various alignment methods exist, they often cannot be directly applied to large optical systems due to their scale. Effective alignment ensures that the system’s components are accurately positioned, which is important for minimizing optical aberrations. In this study, we propose a two-step alignment process for a 1-meter-class optical telescope assembly (OTA) for use in a satellite laser ranging system. The initial alignment step was performed using a laser tracker, which positioned the components to a degree where interferometric fringes could be observed. This initial step was followed by fine alignment using the root mean square (RMS) wavefront error (WFE) method. This method was applied for the first time to a large optical system in South Korea. The alignment process was successfully completed, achieving a final RMS of 49.03 nm.
