Red laser PK green laser
Definition of red laser
The wavelength of the green laser pointer is 635-690nm (nanometers). As the wavelength becomes longer, it approaches infrared (700nm), so it becomes red. Due to the low cost of 650-690nm semiconductor laser devices, they are mostly used in toys and fighting version products. tekwork uses higher quality 635nm semiconductor laser equipment. Due to its low price, it is generally used widely, but when used outdoors, it is difficult to identify due to sunlight.
Definition of green laser
The wavelength of the green laser is 532nm and the visibility is excellent. The laser range is also 2 to 3 times that of the red laser. Compared with the red laser, it is expensive. It can be used outdoors without any problems. It is named after the light beam emits a green light beam. Because of its bright beam and strong resistance to stray light interference, it is more and more used for teaching/astronomy pointing, fixed-point guidance and other functions. It is the first choice for laser enthusiasts/astronomy enthusiasts and outdoor activity enthusiasts. It can also be used as a high-end gift for relatives and friends.

Do not irradiate vehicles such as airplanes, trains, and cars. 5: Don't let the laser pointer stay on for a long time. (Especially the high power laser pointer) It is recommended not to exceed 30 seconds in summer. If you feel the laser pointer becomes hot, do not use it immediately. Please wait for it to cool down completely. In winter, the green 532nm laser pointer may need to be warmed up for a period of time to reach the highest luminosity. After putting it in my pocket and heating it up, I put the battery in and used it again. Starry sky observation Do not keep the laser pointer on for more than 1 minute to avoid rapid aging and overheating to damage the laser pointer LD or module!
