Beautiful USB rechargeable laser pointer
Star pointers should be used with caution. This is an application that requires a relatively powerful laser so that the observer can see the beam tree (not just the end point). In addition, the light beam points to bright objects in the sky. External laser users should be aware that these bright and sharp objects may float in the air. 500mw, any wavelength can be fully burned. Short and long wavelengths mean that the energy density concentrated at one point is higher, so I think that for the combustion power of one point, a shorter wavelength is advantageous. In addition, many so-called laser pointers use semiconductor laser pointers. Due to their characteristics, even lasers have a focus. The energy power varies according to the lens that collects the light. Therefore, even this relationship becomes a kind of burning. the power of. I think this is very important.

In addition to presentations, projecting microbial images, and disabling satellites, handheld high powered laser pointers can now be used for other purposes. This device is a very small and inexpensive laser. Green light is brighter than red light and is often used. Explain the description of the terrain model in the building sales. It is used for teaching during the meeting, the instruction of the driving school, the guide, the explanation for the astronomy enthusiast, the construction instruction, the lighting of the match, the disaster. It has many kinds of instructions such as ward instructions and crows. Use exclusion. Add other electronic functions to the conventional pen laser. For example, connect the head gypsophila effect adapter and rotate it to create a gypsophila design. The ability to write letters will also increase. LED flashlight function, 2 colors in one, 3 colors in one, 2 colors laser + LED function, 8 in 1 gypsophila design, 6 in 1 gypsophila design, safety lock function, etc.
