Average usage time: 1pc per month Sold per unit / ea. ------------------------------ Understanding the Role of a Focus Lens in Laser Welding A focus lens in laser welding is a critical optical component that concentrates the laser beam into a precise, focused spot. This focused beam increases the laser's energy density at the target area, allowing for precise and efficient welding. The focus lens is essential for achieving high-quality welds, as it directly influences the spot size, penetration depth, and overall accuracy of the weld. Properly focusing the laser beam ensures that the energy is concentrated where it is needed most, minimizing heat-affected zones and reducing the risk of defects in the weld.
