Uncompromising performance

The 405 nm 30 W High Power Fiber Coupled Diode Laser is a specialized ultraviolet-violet light source designed for the most demanding industrial and scientific applications. Operating at the 405 nm wavelength, this module provides the high photon energy required for precise photo-chemical reactions, making it the definitive engine for laser direct writing (LDW), digital imaging, and high-speed UV resin curing. Delivering a potent 30 W of continuous-wave output through a high-brightness 400 µm fiber core, the K405 series utilizes a sophisticated 4-submodule architecture (60V per module) to ensure maximum spectral stability and power consistency. Built for 24/7 heavy industrial environments, this water-cooled system ensures absolute thermal protection even during long-duration procedures. Terminated with a pluggable SMA905 interface for rapid field replacement and integrated with technical thermal monitoring, it represents the industrial standard for 3D printing (SLA/DLP), biological detection, and advanced lithography research.
