If you are looking for a high-power laser pointer, there is no doubt that you will find many strengths and colors to choose from.
But what about the different laser pointer functions? What is wrong killing and what is wise? Can I apply for specific features?
Let's take a look at the most common laser safety and usage features, what they do, and why you should not look for them.
When you can actually control the required beam width, you can aim at objects with greater precision over longer or shorter distances.
Because the beam of the aiming beam will widen as the beam moves outward, being able to make the beam thin will keep the beam longer. This is very useful for many different applications when you reduce the difference.
This is particularly important for combustion lasers.
Now, no matter how you focus in a short distance, a laser of 500 MW or higher can "burn", but if you are trying to launch a balloon from 50 feet away, you need to make sure that the beam is well focused and increase the burning heat as much as possible. strength.
Here, the use of focusable elements will be very different.
Various lasers will have a key switch locking mechanism, unless the key is connected and activated (even if they are rechargeable batteries), they are not allowed to be turned on.
Now you can remove the key so you don't have to use the laser while the key is hanging, which is a good security feature for those who don't want children or any unauthorized person to use them.
For untrained or inexperienced people, they may use lasers in dangerous or wrong ways. Its scope is simple, such as looking down when opening the aperture (it is dangerous for the eyes), aiming at a friend, or aiming at something worse (more dangerous and illegal), such as an airplane or a motor vehicle.
In this case, when the laser cannot be monitored all the time and you have concerns, just use a laser pointer with a key switch safety mechanism to completely eliminate these concerns.
Therefore, depending on your situation, whether it is a classroom, home, office, or laboratory; the key switch may be essential, but it seems too large for most everyday users.
This will depend on the laser you plan to use. If you want to use a laser pointer to point out the content on the classroom blackboard or projector, the simple AAA laser pointer style may be the best choice.
You can use it simply and intermittently through the buttons on the body. You do need to hold the button, but for this short-term switch, this may be your best choice.
If you plan to turn on the laser for a longer period of time (for example, 20 seconds or more) at a time, or you want to use it outdoors and in the wild, the tail cap button is better. The attraction behind the tail cover button is that you can turn on the laser and it will stay on.
You don't need to hold down the button to keep the laser working. This means you can open it and use a closer beam, or move to another area where the laser remains active.
For users, this is a good choice and a typical choice. You will notice that almost all high-power combustion lasers use rear cover button switches.
