The 405 nm 160 mW Fiber Coupled Diode Laser is a high-brightness technical source engineered for applications requiring meticulous thermal interaction and superior beam quality. Characterized by its ultra-narrow 40 µm multimode fiber core and 0.22 Numerical Aperture (NA), this module provides an exceptionally concentrated energy density that is the industrial standard for Computer-to-Plate (CTP) thermal imaging and Computer-to-Screen (CTS) digital exposure systems. Built for long-term operational stability, the K405 series operates with a 20% electrical-to-optical conversion rate, specifically tuned for low-noise performance in scientific environments. Featuring a standard FC-Ferrule termination and a compact, rugged industrial housing, it delivers the consistent, reliable 405 nm violet output required for advanced medical diagnostics, fluorescence excitation, and precision laboratory instrumentation.
