2. Core Technical Advantages

The 375nm wavelength perfectly matches the absorption peak of photoresist, solder mask ink and photoinitiators in UV polyurethane systems. It delivers higher light absorption efficiency than 405nm lasers, generates sharp pattern edges and achieves sub-micron patterning, significantly improving production yield for PCB, microfluidic chips and semiconductor substrates. Equipped with built-in TEC temperature control and constant-current driver, the module features outstanding power stability and low optical noise, supporting high-speed TTL modulation. Multiple fiber core sizes (105μm/200μm/400μm) and SMA905/FC connectors are optional with high coupling efficiency. With compact modular construction, air-cooled or water-cooled thermal solutions are available for long-hour continuous stable operation. It is ideal not only for industrial mass lithography exposure, but also for selective spot curing of polyurethane and UV adhesives without massive thermal damage.

3. Wide Application Fields

It covers industrial precision manufacturing and scientific research. For industrial use: LDI lithography, PCB imaging, selective UV curing of polyurethane and micro-structuring. For laboratory research: fluorescence excitation, bio-detection and material spectral analysis, delivering reliable fiber-coupled UV laser solutions for advanced precision manufacturing.
