The Polaris is the world's most powerful visible-wavelength blue portable laser. Cutting-edge 447 nm laser diode technology brings power levels previously only possible using bench-top blue lasers at a fraction of the cost. Its ground breaking 447 nm wavelength is not only captivating but can also produce fluorescence effects in some materials. Diode technology means energy efficiency, allowing this laser to operate three times as long as DPSS blue portable lasers. Available in power levels from >100 mW to >1 W sustained output with a 100% duty cycle. >500 mW and higher models include free laser safety goggles.
