Your laser pointer beam can go into space

Laser is a high-energy coherent and extremely concentrated focused electromagnetic wave. But it will eventually pay remotely. I am not a green laser pointer expert by any means, but I think one of the reasons is that the beam itself consists of multiple wavelengths. There are countless wavelength starting points between any two consecutive peaks in the…

There is currently no treatment that can repair pen damage

I accidentally looked at a green laser pointer spot for about a second, and now there is a blind spot in the middle of my field of vision. Is this permanent? If you look at the light spot reflected/scattered from the wall or paper, and the distance is more than 5 feet, and it is not a…

Is the green laser more dangerous than the red laser?

Why does my green laser pointer (532 nm) turn yellow when it touches the orange part? It will not change the color on any other surface. Due to the fluorescence of the surface material/pigment/paint. Usually we can observe it with ultraviolet light or at least a blue light source. But F. means consuming certain wavelengths of light…

The laser pointer beam is located inside the fiber

Can you pass a safety laser with a mirror? You mean like in the movie? Who designed such security? That is a defeated system. Let me give an example of a safety laser. The optical fiber is buried in the gravel “moat” surrounding the facility. Fences are usually used with optical fibers. The laser pointer beam is…

There is no visible laser pointer in imminent danger

If I get lost in the wild, but I have a laser pointer, can I point it at the airplane to draw attention for help? It is illegal to point the laser pointer at the aircraft at will. Now I have added that dazzlingly obvious statement to my answer in the editor. With a little digging,…

Do I really need a laser pointer or light on my gun?

How accurate is the laser rangefinder? The unit’s documentation will tell you that its capabilities vary from model to model. The important thing is to learn to use the system and practice within a known distance until you learn how to aim the unit. Aiming and getting the beam you want is an acquired skill….

The laser pointer sensor is really safe

Not only can “power” users be used, can any other species invent a laser pointer or dagger that can retract the laser blade? Well, there is a laser type weapon called the energy sword. It is made of plasma-almost their version of lightsaber (saber is just a sword). Variants include blood blade, plundered silver, and green variants….
