Adjustable focus green laser pointer

Different colors of laser irradiation, the optical effect and the resulting colloidal solution is different. When light is directed to the dispersion, only the light from the rest is absorbed, scattered, or reflected. The green laser pointer absorption of 200MW depends on the chemical composition of the system, which in turn depends on the dispersion of scattering and reflection. If the particle size of the dispersed phase is larger than the wavelength of incident light, especially the reflection and refraction of light, if the particle size is smaller than the wavelength of incident light, the scattering mainly occurs when the light is observed around. Light radiates into surrounding particles called flares or opalescent. Tyndall effect is a light scattering phenomenon or opalescence phenomenon. Because the particle size of the sol is between 1 and 100 nm, if the purchase is a large current excellent green laser pen, most of the styles you need around you can be 2000mW blue laser pen, of course, the more electricity is more suitable for burning laser. If your current can be higher and used in the same lighting style as, say, popcorn balloons, the laser will generate a reasonable amount of heat.
