The power laser pointer has special powerful functions
How is the brightness of an ultra-high power laser pointer affected? A: The brightness of the light emitted by the high power laser pointer depends on the output power of the laser and the vision of the human eye. For example, the human eye is most sensitive to green light with a wavelength of 520-570 nm. Less sensitive to red and blue. So even though it's the same efficiency, the green is more visible. If you want clear light, choose green. Business, office people - can be applied to product demonstrations and lectures! The green light gives a refreshing, energetic feeling. You can easily explain the product in front of customers and make it look good. The laser output for this application is approximately 15mw or higher. 3. Laser pointers for conference speakers, museums, exhibition halls, and tour guides can easily and accurately point out unreachable goals. It's convenient and stylish. The laser output for this application is approximately between 20mw and 50mw.

Why is the laser from a green laser pointer brighter?
Is the strong laser from the laser pointer green, red, blue, or yellow? It depends not only on the output of the laser pointer and the reflectivity of the surface, but also on the sensitivity of the human eye to color. Because the eye is most sensitive to green lasers with a wavelength of 495-570 nm. A green laser appears brighter at the same output because it is less sensitive to red or blue laser wavelengths. The most common is a green laser with a wavelength of 532 nm, which is clearly visible at night even with low power lasers. A 5mW laser is the safest way to use it.
The green laser pointer repels the crow The laser pointer effect is 100%, which directly illuminates the crow with a green or green laser pointer star. Birds are sensitive to green or red laser pointer crows. Scientists have invented a weapon that can repel birds. 3000mw (3W) 532nm Laser Mosquito Repellent. Devices that emit laser beams, typically used in industrial and medical astronomical lasers, have built-in safety circuits. This is used to protect the laser pointer from being too strong. But many things sold in toy stores are imported from abroad to reduce costs and reduce costs, so this protection device is not installed. In other words, in order to directly convert the energy provided by a battery or the like into light, an intense beam of light far exceeding expectations is emitted.
