Core Industrial-Grade Advantages

1. 435nm Deep Blue Light: High Photon Energy & Optimal Material Interaction

• 435nm (±5nm tolerance) deep blue light features a 3.06eV high photon energy—10% higher than the mainstream 450nm blue light, with stronger photochemical reaction activity and higher absorption efficiency for special photoresists, UV-curable adhesives, and fluorescent probes. It can realize high-precision material processing and efficient fluorescence excitation that 450nm blue light cannot achieve.

• Narrow spectral linewidth (≤5nm FWHM) eliminates chromatic aberration of optical systems in processing/detection equipment, ensuring uniform energy distribution at the fiber output end and avoiding local over-irradiation or insufficient reaction in processing. No stray light and pure spectral output, avoiding interference with the weak electrical signal detection system of scientific research instruments (e.g., flow cytometry, confocal microscopy).

• The wavelength falls in the optimal absorption window of a variety of industrial special materials (e.g., semiconductor photoresists, high-temperature resistant UV-curable composites) and biological fluorescent probes (e.g., DAPI, FITC), achieving 85%+ photochemical reaction/fluorescence excitation efficiency and significantly improving processing/detection efficiency.

2. 6W High-Power Stable CW Output: Meets Industrial High-Throughput Demand

• 6W industrial-grade stable CW output (0–6W stepless adjustable) covers the full power demand of medium-to-high power blue light applications: low power (0.5–2W) for biological fluorescence excitation and material surface detection, medium power (2–4W) for high-resolution SLA 3D printing and PCB fine lithography, high power (4–6W) for semiconductor micro-nano processing and thick-layer UV-curing—one module adapts to multiple application scenarios.

3. High-Precision Fiber Coupling: Uniform Energy Delivery & Flexible Integration

• It can be equipped with 105μm UV-grade multimode silica fiber (NA=0.22) specially optimized for 435nm deep blue light transmission—low optical loss, high temperature resistance, and no fiber aging or power attenuation caused by long-term blue light irradiation.

• 
  

• Upgraded industrial-grade space coupling system with dual aspheric glass lenses, achieving coupling efficiency ≥85%—minimizing optical loss and ensuring maximum effective power transmission to the processing/detection site. The fiber coupling end is sealed with high-temperature resistant adhesive, with excellent airtightness and mechanical stability, avoiding fiber detachment or energy leakage under industrial vibration conditions.
