Laser Common Sense

Laser is another major invention of humanity since the 20th century, following atomic energy, computers and semiconductors. It is known as the "sharp knife", "ruler", "bright light" and "strange laser". Its brightness is about 10 billion times that of sunlight.
The principle of laser was discovered by the famous American physicist Einstein as early as 1916, but it was not until 1960 that laser was successfully manufactured by humans. Laser emerged in the context of theoretical preparation and urgent production practice. As soon as it emerged, it achieved extraordinary and rapid development. The development of laser not only gave new life to ancient optical science and technology, but also led to the emergence of an entire emerging industry.

Introduction to The Uses of Laser Pointer

1. Teacher/Lecturer - Used for classroom teaching, it is like an infinitely extended whip, allowing you to easily point to the blackboard in any corner of the classroom. It is definitely a powerful assistant for teachers!
2. Business person/conference presenter - Used for product demonstrations and conference presentations, making your speech more spontaneous and communicating with customers more relaxed and natural.
3. Exhibition Hall/Tour Guide - When you are at a loss when facing a goal that is difficult to reach, it can help you easily and accurately indicate the target.
4. Wilderner/Explorer - Used for wilderness exploration, indicating distant targets and issuing distress signals, making your journey happier and safer.
5. Astronomy enthusiasts - Used for pointing stars in astronomy, the green laser beam emitted is a very beautiful green line, which is very suitable for observing the starry sky at night and can help you point out the position of the stars.
6. Construction sites/mining sites - Used to accurately indicate buildings from a distance, which can avoid approaching dangerous areas and make you feel like on-site command from a kilometer away.
7. Self Defense - When you encounter a dangerous animal attack in the mountainous area, or when criminals rob you, posing a threat to your life and property, you can use it for self-defense. Just take it out to scare the other person, don't really make them lose sleep.

Of course not, you can easily point to the horizon with just one click, which greatly enhances your demeanor.
9. Firefighting/disaster relief/distress/earthquake - A life-saving pen for many emergency situations.
Used for classroom teaching, product demonstrations and conference presentations, wilderness exploration, astronomical star pointing, and accurate remote indication of buildings.

Here's Some Cool Info on The Difference Between The Various Colors of Laser

Brightness : Green > Blue > Cyan > Red > Yellow > Purple Light
Price : Red < Green < Blue < Cyan < Purple < Yellow Light
Poly thermal performance ( ignition ) : Yellow < Cyan < Green < Red < Blue < Purple Light
Stability: Green = Cyan < Red = Blue = Purple = Yellow Light ( Green light is influenced by the climate, You may need to warm it up in cold environments)
