(3.5 mm) as like as two peas, Ipin will directly open the laser. It is not the shell with diamond teeth. It is just like the iPhone metal shell. Ipin is a new Laser pointer index. It can also replace the original laser pointer that you use with the downloadable application. With this application, you can connect to the computer where the presentation is performed, and then you can switch slides directly from the phone screen. It can emit amber red laser with 635 nm wavelength. Manufacturers say the laser is longer than the 655 nm used in many stores. Even better, if the audio is transmitted to the audio headset, it will not consume more energy than the mobile phone, so it does not need the heavy battery life.
I believe this laser pen will give me more detailed information and make it easier for me to understand. As before, you grew up in a government agency because you didn't have a video recorder in 2003. It's no longer a procedure to use video remodeling. However, I also agree that simple charts or text tables don't need pointers. During the demonstration, I used this laser pen many times to indicate things or attract people's attention. I use many different pointers. For example, I only use short needles. I also use different types of laser color pointers, such as fingers, circles, boxing and so on. So I can choose different types of epitopes according to what I show today and the performance of the audience
