Is there an application for the laser pointer?
In addition, if you are lost in the wilderness and a search and rescue operation is underway, you will be more likely to be found and rescued because you can see powerful lasers for up to 20 miles at night. All life-saving professionals know the value of strong light that can cover long distances. The higher the milliwatt power, the farther the distance of the strongest laser pointer, the easier it is to see the laser. Depending on the power and color, it can range from a minimum of 1 mile or more to 10 miles or more for high-power devices. So how much range can we get from the 100mW green laser? More than 10 miles. 1,000mW green laser pointer? The range from distance to target exceeds 15 miles. From today's old laser to the new version, the most obvious change is the visible color we see. The only color available in handheld solid-state diode technology is no longer red. Today, almost all visible colors in the spectrum can be used in box laser devices, many of which are also available in portable formats. The most common are green at 532 nm, blue at 445 nm to 450 nm, violet or violet at 405 nm, yellow at 593.5 nm, and of course red at 650 nm.

The life span of a real 532NM wavelength high powered laser pointer is also very different. A real laser crystal can be used for up to 5000-8000 hours, and the lifespan of a sloppy laser pointer may not exceed one week. A sloppy laser can only burn in a short time, so buying a sloppy laser pointer is not a good idea. Whenever buying a laser pointer, people should pay enough attention to whether it is an infrared filter. The best laser pointer should only fit the one you use. Generally, it should be noted that lasers below 175 mW cannot provide enough heat to burn, but lasers above 200 mW generate enough heat to be regarded as burning lasers. If you are looking for a laser that can illuminate matches, etc., make sure that its color is at least 200mW.
