The 520 nm 1 W Fiber Coupled Diode Laser is a high-performance visible green light source engineered for precision-driven medical, industrial, and scientific applications. Delivering a potent 1 W of continuous-wave output through a high-brightness 105 µm fiber core, this module provides the exceptional visibility and energy density required for high-end technical integration.
Designed for superior spectral reliability, the K520 series maintains a stable 520 nm ± 10 nm center wavelength, making it a critical component for fluorescence excitation, underwater communication, and advanced surgical alignment. Housed in a robust industrial package with standard SMA905 termination or fiber depending on your choise and a high-reliability thermal design, it offers the uncompromising consistency required for biophotonics research, industrial lighting, and high-visibility LIDAR systems.
