How to get the 650nm red laser pointer

The special emission of 650nm red laser beam, guiding such a red laser in the dark will bring you a completely different experience. In addition to visible light, some green laser pointers emit infrared infrared (IR) light. For example, the recommended laser pointer tested by the US government agency has a slightly visible green light when outputting 20mW IR (4 times the US legal limit). The 5mW high power laser pointer will project the most beautiful red light on various occasions. Inferior lasers are dangerous because invisible infrared rays are projected when aiming.

It is located in the center of the frame and looks and weighs like a large pen. You can put it in your pocket and use the included clip to secure the device on the go. The best laser pointers are powerful enough to be used while observing the night sky, even under non-ideal conditions. The output of the green laser pointer is 1mW to 30000mW, and the laser can find objects in the sky. This is a powerful laser, so you need to press and hold the power button to use it. Release the button to turn off the laser. This simple design is still one of the most common consumer laser pointers, very suitable for office and educational environments. No one can see the emission of infrared light unless it hurts or hurts human eyes.
