Microscope objective lens housings protect precision optical lenses, requiring high transparency, seamless sealing, and dimensional accuracy, ensuring clear imaging and lens protection. Traditional adhesive bonding affects optical clarity, easy residual glue contamination, while ultrasonic welding easily scratches lenses. DaokeDao laser welding is optimized for medical-grade transparent PC and PMMA materials, achieving non-contact seamless welding, no scratch, no residue, preserving lens surface smoothness and light transmittance (≥92%). The weld has high sealing performance (IP67 rating), blocking dust and moisture, ensuring lens cleanliness and long-term optical performance. The process is cleanroom-compatible, with ultra-high positioning accuracy (±0.003mm), avoiding lens misalignment. The equipment supports miniaturized precision welding, suitable for small-batch customized production of microscope manufacturers, improving imaging quality and lens service life.
