405nm Lasers

405nm laser pointers close to ultraviolet, it is a purple laser pointer, bordering on the very extreme of human vision, and can cause bright blue fluorescence, and thus a blue rather than violet spot. Blue lasers can also be fabricated directly with InGaN semiconductors, which produce blue light without frequency-doubling. Making your travelling fan and interesting, it's truly amazing light show, you'll be surprised with that many stars fill your space.
