Many people still don’t know what is meant by laser pointers even though applications are abundant in the entertainment and scientific fields. I don’t say words like that without reason. I met a friend yesterday and told him I wanted to buy a green laser for a business presentation. He was confused about what the laser could do for the presentation and I explained everything to him. After that, I realized that not everyone knows clearly about laser devices, maybe only professional people or laser followers who are familiar with them.
A laser pointer is a small device that can emit a narrow-looking beam with resources, and is used to highlight objects by illuminating them with small bright spots. Lasers can be separated into many categories, including green lasers, red lasers, blue violet laser pointers and so on. Now green laser pointers have become sheep among all lasers by bright shining rays, clear visibility, low prices and high quality. Green lasers have different output powers, for example, some of which range from 1mW to 1000mW and people choose the right one according to their purpose.
In general, lasers lower than 5mW are safe to use. However, sometimes people have to buy high-power ones to complete their assignments. That’s because many experimental effects cannot be achieved without enough power. The problem is how to meet the various requirements of many people with different intentions?
With a wavelength of 532nm, the output power of the green Helios series pointer laser ranges from 5mW to 150mW and can almost meet all requests from different users. Helios series lasers lower than 50mW are perfect for indoor presentations. Teachers at seminars, business people and interior decorators all use this green laser to help them complete difficult tasks. This is indeed a capable assistant for remote pointers and presentations.
Helios lasers from 50mW to 100mW are mainly used to observe star objects and celestial bodies. Hard explanations and handwaves are no longer needed with laser pointers. The green laser is so bright that you can see the beam even on days, not to speak in the dark. Lasers above 100mW are very useful for people who want to do professional research and combustion experiments. In addition, high-power laser gadgets can be used in hiking and outdoor activities. The laser beam is bright enough to frighten large wild animals and users can send signals for help in the event of an emergency.
