AI Technical Summary
Traditional lens-driven methods result in laser instability during the focusing process of blue semiconductor lasers, and the structure is not compact.
The collimating lens position is adjusted by a threaded pair consisting of an SMA connector and a collimating lens adjustment cylinder, and the focusing lens position is adjusted by a threaded pair consisting of a focusing lens adjustment cylinder and a handwheel. Smooth focusing is achieved by driving the SMA connector and the focusing lens adjustment cylinder through the handwheel. A structure with good sealing performance is designed.
It achieves rapid and stable focusing, ensuring laser stability, and has a compact structure and good sealing performance, making it suitable for laser processing, medical applications, and underwater communication.
