A laser pointer that can play an important role
If you plan to purchase the recommended laser pointer for any of these applications, you should consider the output power you need and the color that best suits your needs. Under the same output power, green is always the brightest. To get visibility beyond 10 miles, you need more than 100mW of output power. Another factor that determines how far the beam is visible is the focus adjustment design feature available on some laser models. USB laser pointers provide the option of narrowing or widening the beam, and are more suitable for long-distance aiming, because they can accurately locate short-distance or long-distance targets. Convergent beams can improve visibility at short and long distances. At least 100mW is required to generate enough heat, the higher the power, the better. The unit of measurement of the laser is milliwatts (mW), depending on the output of the laser, and it can be hand-held with a power range of 5mW to 1000mW.

The green laser pointer is the simplest type of laser pointer, and it can be a battery powered laser pointer. The red laser pointer can completely free the user from the computer. If you need to pay attention to your presentation and report speech, important content, you can map the red laser dot, because you need to tap the highlighted text with your hand. On the screen, you don’t have to “reach” or “close contact” with the audience every time you explain something important. At the same time, users only need to point out the relevant function buttons, and the electronic manuscript can be rotated 360 degrees up and down to the user page freely. Whether in the corner of the classroom, in the auditorium, or behind a meeting room with audiences, the screen will automatically pop up, eliminating the need for a computer.
