Laser shot tester
Adjusting optics, be it a RedDot or a scope / riflescope, can be very time, BB and nerve consuming! The adjustment wheels for height and side are not labeled in the same way and are therefore misleading. An "R" can mean "to the right" but also "when shooting to the right", that is to say move the target green laser pointer to the left or to the right. If you are alone, the "shooting - checking - lowering - screwing around - shooting - checking - lowering - screwing around - ..." is very tedious.A shot tes... more

Evolution ensures that our eyes are fully adapted to sunlight. This
contains more green areas, so our visual organs are more sensitive to
green, which is why the green grass standing on the viewing platform is
easier to attract the eye than the brown-blue water in the same
environment. The light of the green laser pointer is easier to recognize
than the blue one. Therefore, the blue laser pointer must emit much
brighter light than similar Rechargeable Laser Pointer, which is why in the case of poor quality, the upper limit... more

Laser quenching is a surface hardening process. It can only be used
to cure iron-based materials. That is, steel and cast iron with a carbon
content of more than 0.2%. In most cases, the laser beam heats the
metal surface to near its melting point (900-1400 C) to solidify the
workpiece. Even if it is 8 times, it may not be a problem, but if you
compare the same 1mw, for example, the difference is obvious. There are
more than 2W. Generally sold laser pointers are below 1mW, so the output
is as high as 2000 times. Moreover,... more
Among the different color blue laser,

The structure of the red laser pointer is the simplest. The reason why it is simple is that the red laser pointer
is basically just a diode with battery as the energy source. And there
are laser diodes that generate this wavelength. The red laser pointer
first appeared in the 1980s. It is a large and heavy device worth
hundreds of dollars; it is very small and very cheap. The word laser
should be familiar to you.

Some people are high power laser pointer
enthusiasts, they have everything from the main product to the place
where they get it (maybe they made it themselves). If you have never
seen a laser pointer, you may not have read this article, but as you
know, most of the lasers used in laser pointers are red or green. This
is because it depends on the color of the laser diode that generates the
light. As red, green, and blue (RGB: the three primary colors of light)
three light-emitting diodes are widely used in various fields, i... more

What is the Tyndall effect?
If the laser is not directed at you in a vacuum, you will not be able
to see it. However, the air we breathe together is not a vacuum. Among
them are dust, suspended particles and so on. The bright "passage" of
the laser light is formed by the scattering of light by these particles.
We call it the "Dyndall Effect". Light is w... more
