The High Power Violet 405nm 600mW Fiber Coupled Laser Module—a precision-engineered industrial light source optimized exclusively for laser direct imaging (LDI) systems. Integrating 405nm violet lasers’ photoresist-specific absorption, 600mW high-energy output, low-loss fiber coupling, and production-grade stability, it delivers uniform, high-resolution beam performance for PCB/FPC fine patterning, enabling efficient, high-yield electronics manufacturing.

Core Advantages for Laser Direct Imaging

405nm Violet Wavelength: LDI Photoresist Optimization
405nm wavelength aligns perfectly with the absorption peak of industrial LDI photoresists (epoxy, acrylate-based), triggering rapid, complete photopolymerization; supports ultra-fine linewidth patterning (down to 15μm) for HDI boards and flexible electronics, outperforming longer wavelengths in imaging precision.

600mW High Power: Boost LDI Throughput
Stable CW output, high energy density, reducing photoresist exposure time by 40% compared to 300mW modules; meets high-volume production demands for PCB manufacturing lines without compromising patterning quality.

Low-Loss Fiber Coupling: Flexible Integration
Equipped with UV-grade multimode silica fiber (core diameter 105μm, NA=0.22, coupling efficiency ≥85%), enabling precise, flexible beam delivery to LDI scanning systems, adapting to confined equipment spaces and complex motion paths. Fiber length customizable (1–3m) for factory layout flexibility.

Key Applications

Primary Application: Laser direct imaging (LDI) for fine circuit patterning on rigid PCBs, flexible FPCs, HDI boards, and semiconductor packaging substrates.
Extended Applications: UV photopolymer curing, microfluidic chip lithography, and high-precision photomask making in electronics and microfabrication industries.
