How to customize laser pointer pens?

Various lasers have a key switch locking mechanism that prevents the laser from being turned on (even if the battery is charged) unless the key is turned on and activated. Now you can remove the key afterwards without using the laser while the key is hanging. This is a good security feature for children and those who don't want unauthorized people to use the key. It can be any simple thing, such as looking down at the opening when opening (dangerous to the eyes), aiming at a friend, or worse (very dangerous and illegal), such as aiming at an aircraft or a car. In general, the power of the laser pen is 1000MW, which should be designed as a thin line of 0.5mm and a working distance of 0.5m. To ensure ultra clear red lines, this green laser pointer is always equipped with optical glass lenses. This qualified 2000MW laser pen always performs best on a clear and accurate target surface. This energy transfer requires only a few parts of the color of the solar rod: red and blue. But scientists have found that red and blue lasers work better. Our laser indicators are more effective in providing the exact type of plants that need light. After all, as a substitute for sunlight, laser consumes less energy and is environmentally friendly.
