In the assembly process of miniature optical instruments, this stage plays a crucial role. It is made of aluminum alloy, featuring both light weight and stable load-bearing capacity; driven by a micrometer, it can ensure precise adjustment during assembly. The 360° rotation function facilitates assemblers in adjusting the position of parts, while the ±5° fine adjustment enables accurate alignment of Optical Components. This stage effectively improves the assembly precision of miniature optical instruments, ensures the optical performance of the instruments, and meets the application requirements of precision optical equipment.
