Funny laser pointer chaser for cats and dogs
The laser light emitted by the green high powered laser pointeris a solid-state laser. Safety laser The laser of the sword is a semiconductor laser. All lasers are converged through a converging lens, but the solid-state laser is a semiconductor laser with a small divergence angle, so the light energy of the green laser converges. In addition, the super-powered green laser pointer has a high lumen, and the green laser pointer has a longer range than other colors of laser. It can be said that the higher the lumens, the stronger the luminous efficiency. High-quality safety keyed laser pointer, adjustable focus laser and ultra-high output laser pointer make it ideal for presentations. Now sold at a very low price! The high-power laser unique to overseas models can be used for match ignition, special lighting effects, starry sky viewing, driving away crows, pigeons and other harmful birds. The silver body has a metallic texture on the entire surface. Although it is small, it has a strong sense of presence. However, if you look closely at the product, you will find that it has some small scratches. I think this is a level that many people don't care about because it can be seen by adjusting the light, but if you might be worried, please choose another product.

Application
It is said that the green laser pointer, which is easier to see visually than red, can be explained to the audience in an easy-to-understand manner. Even a bright projector with a highly recognizable green laser can accurately display the position. The green laser beam can be irradiated about 200m away. 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 if it is a point of combustion power, a shorter wavelength is advantageous. In addition, many so-called laser pointers use semiconductor laser diodes. Due to their characteristics, even lasers have a focus, and the energy power varies according to the lens that collects the light. Therefore, even in this relationship, I think the combustion power makes a difference. (Night* depends on the environment of use) When irradiating, the button at hand will light up, so you can see at a glance whether it is irradiating even in a dark place.
