Average Reviews:
(More customer reviews)A GaN laser does not require IR or UV filters, because the Gallium Nitride emits light directly in the low 400nm wavelengths. Spectral analysis of this laser shows emissions all the way into the high red spectrum, which indicates that it is probably using frequency doubling technology, which I understand emits harmful radiation, even IF a filter is installed. Furthermore, the laser came in a generic "Green Laser" packaging -- with all completely wrong information. The government labeling looks suspicious too -- different enough from my red 630 laser and lacking specifications enough to make me VERY suspicious. Is this a seller problem, or a product problem? I'm not certain. I specifically chose a seller that charged more for this, and I received confirmation from a DIFFERENT seller that he was "double certain" that his laser was in fact a GaN laser. I highly doubt they can be trusted. If you just want a toy, and don't care about the technology used, (or relative safety) then it seems fine.

Blue lasers are the cutting edge of consumer laser pointers, and this is a fun one. The special lens that caps this laser pointer diffuses the laser beam into patterns that can be adjusted by twisting the lens. If you want to use it like a regular laser pointer, just unscrew the cap.Please note, because the human eye is more sensitive to green than to blue, this laser pointer will appear less bright than a similar green one. However, the milliwatt output is factory-calibrated and accurate. In daylight or bright places, the blue laser will be more difficult to see. In darkness, it is bright.
