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…
Which is better red dot or laser pointer?
How long does it take for the laser beam to hit Mars from Earth’s orbit? Well, the laser pointer beam travels at approximately 186,282 miles per second, so you can calculate the time by dividing the distance by this value. I have posted the approximate maximum and minimum distances between the planets and the sun, and placed…
The airborne laser is the most ambitious laser pointer
What is the best laser? Well, usually putting a laser pointer on a rifle is a bit unnecessary. However, if you really want one, I suggest you use PEQ. These are a little heavier than a single laser, but it is one piece. It is a flashlight, a red laser, and most importantly an infrared laser. There…

Laser pointers in Star Wars look like bolts
Why do the lasers in “Star Wars” look like bolts when they are actually beams?Because without these special effects, the movie is really boring. Just imagine if it was in the real world. Hans pulled the trigger, and at the same time we saw a cloud of smoke, there may be some sparks hitting it….
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 weapon system currently in use by the Navy
How does the laser work? How realistic is the laser pointer gun in the science fiction movie? What would a realistic laser gun look like? For example, this is the laser weapon system currently in use by the US Navy: Obviously, it can disable missiles, drones, and boats by overheating electronic equipment. Compared with more classic weapons,…
