In modern law enforcement operations or war conflicts, we often see special forces members with a delicate box on their guns.
(The first and only LAPD SWAT female player - Jennifer Glasso ( ) interview video "The first and only LAPD SWAT" is installed on its HK416 with a company-produced DBAL-A3 laser indicator))
Although this kind of equipment may differ in application scenarios and functions, most of them can be classified as the category of laser indicators in gun accessories.
Moreover, not only military and police units, but even among the American people, regardless of the length of weapons, more and more people will choose to install a laser indicator on their love guns. (regardless of whether it has IR capabilities or not)
The reason for installing is also very simple.
1. For gun training, laser lasers visible to the naked eye can be used as indicators of the muzzle to display and avoid potential errors during weapon operation.
For example, there is one of the "Four Principles for Use of Guns Safely": All guns must always point to a safe place; the specific operation method is to imagine the muzzle as a laser that destroys everything at all times, and the muzzle pointing will be destroyed, so you must always pay attention to the pointing of the muzzle.
(To avoid such strange things)
Therefore, a visible laser ray can make the shooter pay attention to the pointing problem of the muzzle, so as not to hit something that should not hit during operation...
At the same time, it can also help and guide novices to correctly find the right relationship between the sight and better aim at the target. Because friends with a little bit of shooting experience understand that even small things like where the shooter stands (whether it is on the ground) and psychological pressure (finger tremble when pulling the trigger) may have an impact on his shooting results.
A visible laser ray can completely allow the coach and the shooter to see clearly the pointing of the muzzle when pulling the trigger, thereby further correcting the action of pulling the trigger or holding the gun.
Therefore, Dry Fire, which is known for its low-cost and can be carried out anywhere, has also become popular. Paired with a visible laser from the naked eye, it is more conducive to novices to prevent bad shooting habits during training, and improve other technologies such as trigger control and mobile aiming. Moreover, this combination is often simpler, more convenient and cheaper, and the training effect is intuitive and visible.
(Now there is even a laser emitter equipped with an AR bolt, which directly replaces the AR bolt, allowing the laser to be directly fired from the gun chamber to simulate the close-range bounce point)
In previous programs, the editor talked about a lot of situations in which American gunmen installed laser indicators. In addition to taking your shooting level to the next level, it also makes it easier for you to play more accurately in various unconventional and uncomfortable postures. It also makes it convenient for you to reduce the exposed area of your body after the cover and shoot at the same time.
This also proves that laser indicators can expose themselves to enemies less than mechanical or other optical sights.

Even in one-handed shooting, left-hand switching, moving shooting, shooting and moving targets, etc., the results of using laser indicators are much better than when there is no laser indicator installed. After all, lasers visible to the naked eye will often help reduce the energy and psychological pressure of the shooter aiming when the shooter needs to concentrate on other things. In other words, it can be seen that the laser allows the shooter to maintain the perception of the on-site situation while focusing on threats and prevent the occurrence of narrow vision.

At this time, the shooter can adjust his tactics accordingly according to the distance and status with the target, and choose to stick or move.
You can even remove the laser indicator as a prop to attract opponents' attention and firepower, and you will unexpectedly conquer and win the lead.
Therefore, it can be seen that when facing targets with poor line of sight, visual environment, and unavailable to aim with the sight, it is a good choice to install laser indicators.
Moreover, the deterrent effect of laser indicators is also online, and it is also an "international language". Influenced by various gunfight movies, no one wants a bright red or green spot to suddenly appear on their bodies, whether it is the drunkard who broke into your house or the restless crowd.
If you are a law enforcement officer, a visible laser spot will also allow every colleague present to see which suspect you are aiming at.
But not any laser laser visible to the naked eye can reach the level of gun use.
Because not talking about zeroing, stability, battery capacity and other issues, lasers are divided into different levels in terms of power, and these levels are classified according to the risk of the human body by lasers.
Taking the MPE ( , the maximum possible impact) on the eyes as a benchmark, lasers can generally be divided into one to four levels. At the same time, laser product manufacturers should also paste warning labels such as Class II, III and IV on the corresponding laser products.
(Common marks for laser MPE grade)
Class I() is a low output laser (power less than 0.4mW), which will not exceed the MPE value for the eyes and skin under any conditions, and will not exceed the MPE value even after focusing through the optical system. It can ensure design safety and do not require special management.
Typical application tools include laser teaching sticks, CD players, CD-ROM equipment, geological, exploration equipment and laboratory analysis instruments, short-distance communication transmission, etc.
(The MPE and power of this laser from CD machine are not high)
Class II () is a low-output visual laser (power 0.4m~1mW), and the reaction time of a person closing his eyes is 0.25 seconds. The exposure calculated during this period cannot exceed the MPE value.
Usually, lasers below 1mW will cause dizziness and no thinking. You can use closed eyes to protect them, but it cannot be said that lasers of this level are completely safe.
First of all, do not observe directly in the beam, and do not use Class II lasers to directly illuminate other people's eyes. At the same time, avoid using remote-looking equipment to observe Class II lasers.
Typical laser tools at this level include classroom demonstrations, laser teaching sticks, aiming equipment and rangefinders.
(E-teacher stick)
Because the power is less than 0.4mW, it is harmless to the eyes. But because its irradiation distance is not more than 1 meter, it is impossible to use it on instruments that require long-distance irradiation.
() is a medium output laser. If the beam directly shoots into the eyes, it will cause damage. Based on certain safety reasons, it is further divided into IIIA (3A) and IIIB (3B).
Level IIIA is a continuous laser with visible light, outputting a laser beam with a power of 1~5mW, and the energy density of the beam does not exceed 25W/mm.
When using this level of laser, you should also avoid using a remote device to observe the IIIA laser, because this may increase the risk of equipment damage (such as causing bad points).
(In the riots in Hong Kong, my country in 2019, many terrorists used this MPE-level or above laser indicator to fight against the police and their video recording equipment)
(On November 15, 2019, the police in Santiago, the capital of Chile also suffered "laser baptism")
(In order to deal with the laser threat, Hong Kong police had to take sunglasses to the police at night, or put a colored laser absorption film on their helmets to reduce the brightness of the laser when exposed to the laser)
Typical application tools of IIIA have many similarities with Class II, such as laser guides, laser scanners, etc.
Continuous lasers with grade IIIB of 5~500mW are still dangerous to observe directly in the beam. However, the minimum irradiation distance is 13cm, and the maximum irradiation time is less than ten seconds.
(In 2020, a Los Angeles policeman was exposed to his eyes by laser while suppressing the riot, causing his eyes to be partially blind)
Typical application tools for IIIB lasers are spectrometry instruments and entertainment lighting performance props.
(): High output continuous laser (greater than 500mW), high, there is a risk of fire, and diffusion reflection is also a risk of. Typical applications include surgical laser scalpels, tools and instruments such as research, cutting, welding and micromachining. Therefore, not any laser can reach the level of gun use.
(At a press conference held by the Hong Kong police in 2019, a laser burning effect was demonstrated at a close distance (about 0.5 meters))
Although the laser indicator is so excellent, it still has its shortcomings. Therefore, in the next episode, the editor will talk carefully about what seemingly perfect laser indicators have in mind and how to adjust them. Please stay tuned for everyone!
