This laser outputs light in the 405 nanometer wavelength which produces a very unique blue-violet color beam, that is unusual for a handheld pointer. This is also the same wavelength used in Blu-ray DVD players. The shorter wavelength allows more data to be stored than on a standard DVD which uses a red laser (650 nanometer).
This laser is certainly awesome but it's also useful for applications such as biomedical instrumentation, imaging, spectroscopy, laser induced fluorescence sensing, microscopy. And if you're not into any of those activities, then this laser can be used to write on photoluminescent material like our Glow Graffiti.
