There is also a brighter laser pointer on the market now with a wavelength of 533 nm (green). The new technology uses a dual-frequency neodymium:YAG laser, which blocks infrared components. Compared to a mildly bright bulb that consumes tens of watts instead of milliwatts, a 5mW laser pointer can barely hear or not hear at all. However, simple laser pointers are highly centered in narrow beams. So today we have 5mW 640nm blue laser pointer beams and they are very bright. Rather, it is a practical laser device for laser alignment, targeting, hunting, search and rescue, outdoor and hiking.
Long-range green laser pointers have other reliable properties such as compact system length, small spherical aberration, and a fully multilayer optical lens system. The amplified coherent light makes it efficient to illuminate armies on the battlefield at long distances. In short, laser pointers are useful tools, but they must be used responsibly. Common sense dictates that users should not point the laser pointer beam at another person. And lasers with power greater than 5mW should not be used as pointers.
Application of long-distance laser pointer
- Hunting and targeting: Wildlife observation, military targeting, detection at long distances without being noticed and raising alarms.
- Search and rescue in all weather and terrain conditions: Visible beams up to 3 miles allow quick and easy location of rescue sites.
- Outdoors and Hiking: Adjustable focused beam with 10x expansion brightens the road on any outdoor terrain. It is an energy-saving device for long-term outdoor survival.
Some backyard astronomers prefer to use high powered laser to find finderscopes. The main reason is that lasers don't require you to bend over to look at objects every time you look for them. This is especially useful when the scope is set at a lower altitude, requiring you to duck, sometimes for a few minutes at a time or if you have back problems. Lasers come in all sorts of fancy shapes and sizes. From small laser keychains to large lightsaber flashlights, if you happen to be a Star Wars fan! As a backyard astronomer, all you need is a medium-sized green laser pointer. Laser pointers developed for astronomy are easy to find, and we recommend three in the table below.
