The instrument serves as an autocollimating collimator, facilitating accurate testing of long guide rail straightness, surface perpendicularity or parallelism, and aperture concentricity. Furthermore, it functions as a focusing telescope for inspecting and adjusting high-precision optical lenses during the manufacturing process. This instrument is essential for research institutions, universities, optical instrument manufacturers, component processors, and measurement units.
