Product Overview:

This Lumics laser diode offers an optical power of up to 4 watts from a 105 µm core, NA 0.22 multi-mode fiber coupled module. At this common wavelength, our 808nm laser diode offers a very competitive price-performance value for applications in materials processing, illumination and medicine. Very high life time is achieved due to the Lumics proprietary laser diode facet passivation technology and due to extensive burn-in testing.
