405nm 12W Free-Space Fiber Coupling Laser Module

The High Power 405nm 12W Free-Space Coupling Fiber Laser Module—a heavy-duty industrial-grade light source engineered for high-throughput precision processing. Integrating 405nm violet wavelength’s superior material absorption, 12W ultra-stable CW output,  this module is tailored for PCB Laser Direct Imaging (LDI), microfabrication, and advanced polymer processing, delivering unmatched efficiency and flexibility for industrial production lines.

Core Advantages for High-Power Precision Processing

405nm Violet Wavelength: Ultra-High Material Absorption Efficiency

405nm (±5nm tolerance) wavelength aligns with the absorption peaks of acrylate-based photoresists, polymer composites, and non-ferrous metal thin films, achieving 4–6x higher energy utilization than 1064nm IR lasers. This enables sub-10μm fine patterning with minimal heat-affected zones (HAZ), avoiding material warpage or deformation in precision processing.

Free-Space + Fiber-Coupled Dual-Mode Delivery: Flexible Industrial Adaptation

• Free-space Coupling output: Collimated Gaussian beam with small spot size and beam divergence, supporting large-area uniform irradiation (e.g., full PCB panel exposure, polymer surface modification) without complex optical expansion systems.

• Fiber-coupled output: Equipped with UV-grade multimode silica fiber (core diameter 200μm/400μm optional, NA=0.22, coupling efficiency ≥85%), enabling precise energy delivery to confined spaces, robotic processing arms, or microfabrication stations—no line-of-sight restrictions.
