Some caches require Rechargeable Laser Pointer. For example, it may be that you have to illuminate a special point, or you have to locate the path with the help of a laser pointer beam. It may not be enough for the green 10000mw laser, and it may be tight for the red laser. The transistor will overheat, then die due to a CE short circuit, and then a full 12V voltage will come to the laser and... will not flatten in the dark season, but this movie is also suitable for other purposes. Shine it with a laser pointer! The color of the laser pointer is usually not that important. Even before we started the treasure hunt, we had a pointer that could be green or red.

In our opinion, it is not necessarily the most expensive pointer, because it is not often needed, and one color is sufficient. Researchers from the University of California, San Diego demonstrated the world's first laser pointer based on an unconventional wave physical phenomenon called the continuum bound state. This technology can completely change the development of surface lasers, making them more compact and energy-efficient in communications and computing applications. The new BIC laser can also be developed as a high-power laser for industrial and defense applications.

Check the webcam with a laser pointer

You can use the webcam to check if your own laser pointer is classified as having IR leakage radiation. I came across a website that built a blue high powered laser pointer into the weapon, that is, where the return spring was "pulled over", a new piece of metal was integrated with the laser pointer. The laser is built into the bracket under the barrel. The only thing that prevents me from buying this is the price.

When it comes to performance data, there is a lot of nonsense. I have two 500mW class 3R green light laser pointer. High-quality products and brand-name products. Both obviously have their own merits. The green laser only looks brighter than the red laser because the human eye is more sensitive to green. The "destructive power" is the same as the same powerful 3000mw laser pointer. Who is the light one? I am well aware of the dangers posed by green lasers. I am also seriously considering it. So it is not a "cool, I want it" toy for me.

Generally speaking, I will not look at blue laser pointers that go beyond the small red laser pointers in the lecture. Inexpensive blue laser diodes with a wavelength of 635-750 nm are commonly used, as well as green (490-575 nm) and significantly more expensive orange to yellow (575-635 nm) and blue (405-490 nm) laser pointers are available .

Does the red laser pointer hurt your eyes? Yesterday, I consulted an ophthalmologist at Taihe Hospital. "The light emitted by the laser pointer does irritate people's eyes." Ita said that if short-term exposure, people's eyes may experience tingling, dryness, and foreign body sensation afterwards, because human eyes have self-healing ability and will gradually recover, but Long-term contact may cause damage to the macular area of ​​the retina of the human eye. The macular area is mainly dependent on the macula. Once damaged, it will of course affect vision and even permanent damage.
