The 3D Jet Monitoring System is a revolutionary optical system developed exclusively for inline dispensers and mounted on jet valve nozzles. Its core real-time droplet visualization function solves issues such as droplet volume fluctuation, nozzle inconsistency, satellite formation, and residue, providing an intuitive presentation of the complete dispensing process. Emerging laser bionic technology supports the drawing of 2D/3D surface microstructures and patterns. It optimizes material properties like conductivity and bonding strength, and adjusts wettability and hydrophobicity. It also offers advantages such as coating protection and anti-reflection, specifically overcoming surface property challenges.
