High Power 425nm 6W Spatially Coupled Fiber Laser Module for Fluorescence Biological Detection& LDI Machine

High Power 425nm 6W Spatially Coupled Fiber Laser Module for Fluorescence Biological Detection& LDI Machine The High Power 425nm 6W Spatially Coupled Fiber Laser Module, a dual-purpose industrial-grade light source optimized for fluorescence biological detection and laser direct imaging (LDI) machines. Integrating 425nm UV lasers’ dual-scenario wavelength compatibility, 6W high-power output, spatially coupled beam shaping technology, and precision fiber transmission, it delivers high-energy, uniform laser beams for high-sensitivity biological analysis and high-resolution PCB/FPC lithography. Core Advantages 425nm Wavelength Dual-Scenario Optimization 425nm UV wavelength matches the absorption peaks of common fluorescent dyes (e.g., FITC, Alexa Fluor 488) for fluorescence biological detection, enabling high-sensitivity cell imaging, molecular diagnostics, and microbial analysis; it also aligns with LDI photoresist sensitivity requirements, supporting ultra-fine linewidth patterning for PCB/FPC manufacturing. 6W High Power for High-Throughput Processing Stable CW mode output with lower power fluctuation provides high energy density; cuts fluorescence detection exposure time by 60% for high-throughput lab testing, and reduces LDI patterning cycles by 40% to meet mass production demands of electronic manufacturing lines. Spatially Coupled Beam for Uniform Performance Advanced spatially coupled optical design generates a flat-top beam profile with ≥92% uniformity; eliminates beam hotspots that cause biological sample damage in detection scenarios and avoids photoresist overexposure in LDI lithography, ensuring consistent results across both lab and industrial applications. Fiber Transmission & Industrial-Grade Stability Equipped with UV-grade silica fiber (core diameter 150μm, NA=0.22, coupling efficiency ≥85%), it enables flexible beam delivery to confined detection chambers or LDI scanning systems. Key Applications Fluorescence Biological Detection: Cell viability analysis, immunoassay fluorescence excitation, flow cytometry, and microfluidic chip-based molecular diagnostics in clinical labs and research institutions. LDI Machine Processing: Ultra-fine PCB circuit patterning, flexible electronics (FPC) imaging, semiconductor packaging lithography, and high-precision photomask fabrication.
