How to choose the strongest laser pointer in the world?
When choosing a good 3000mw laser pointer, these factors need to be considered: laser power, laser crystal quality, lens quality quality LD (bulb) that affect the quality of the laser beam. So be careful of the following points when choosing a laser pointer:
Carefully observe light spots Poor light spots, if there is laser light around a particular flood that indicates that the lens has failed.
Observe if the spot is a perfect black circle;
green laser pointing to an astronomical star 100mw green laser pointer
If the laser light is intermittent, he carefully observes that LD is not very good.
Instant ignition, match, easy to burn cigarettes, travel / mountaineering / exploration It will be more fun if used for outdoor adventures, etc. It is used because of its high visibility. This is because products that are commonly used as Rechargeable Laser Pointer also have legal output restrictions, so even with the same output, more "easy-to-see" colors make more sense. The higher the output, the higher the visibility. For example, even with the same high-power laser pointer, the green laser is easier to see than other colors. In addition, there is an opinion that it is easier to find a green laser at a discount than a red laser for use in surgery and visual recognition by people with congenital color vision deficiency.
DPSS (diode-pumped solid-state laser) type blue laser pointer have become popular at low prices, but they are generally more expensive than red laser pointers due to the large number of parts as optical equipment and complicated electronic circuits. Tend. There are differences in output stability and impact resistance when dropped depending on the product grade (price range). In particular, since the temperature characteristics are more severe than those of red laser pointers, some low-priced products cannot be irradiated for more than several hundred seconds, and some products clearly state that they cannot be irradiated for a long time. As described above, since the light spot of the blue laser pointer is difficult to see in the image of the same color, the green laser pointer can be selected in the image having a lot of red in the background color.
