High Power 405nm 12W Violet Fiber Coupling Laser Module for Lithography Equipment

The High Power 405nm 12W Violet Fiber Coupling Laser Module is a premium industrial light source engineered for professional lithography equipment. Integrating 405nm violet lasers’ photoresist-specific absorption, 12W high-energy output, precision fiber coupling transmission, and industrial-grade stability, it delivers uniform, high-density laser beams for high-resolution patterning, ideal for semiconductor manufacturing, PCB fine circuit lithography, and MEMS device fabrication.

Core Advantages

405nm Violet Wavelength Optimized for Lithography

405nm wavelength precisely matches the absorption peak of industrial positive/negative photoresists, enabling efficient photopolymerization with minimal thermal substrate damage; supports ultra-fine linewidth patterning for high-density integrated circuits and micro-devices, outperforming longer-wavelength lasers in lithography resolution.

12W High Power for High-Throughput Lithography

Stable CW mode output with lower power fluctuation provides ultra-high energy density, cutting photoresist exposure time by 60% compared to 6W modules; meets the mass production demands of semiconductor and PCB lithography lines, significantly boosting manufacturing efficiency.

High-Efficiency Fiber Coupling for Flexible Integration

Equipped with UV-grade silica fiber (core diameter 200μm, NA=0.22, coupling efficiency ≥85%), it enables lossless, flexible beam delivery to lithography equipment’s scanning systems; it eliminates mechanical alignment errors, adapting to confined equipment spaces and complex motion paths.

Key Applications

Perfect for lithography equipment in semiconductor chip manufacturing, PCB fine circuit patterning, MEMS (Micro-Electro-Mechanical Systems) device fabrication, and advanced packaging lithography processes; also applicable to high-precision photomask making and microfluidic chip lithography.

It features a long service life, supports factory direct sales and customization, and applies to a wide range of fields—including LDI, medical analysis, fluorescence excitation, material processing, biochemical research, criminal investigation, and UV exposure.
