real laser pointer online sale

The pointers favored by stargazers used the neodymium laser diode real laser pointer and emitted a green beam with a wavelength of 532 nm. At a given power set, these lasers are brighter than a normal diode laser, which produces a red beam that’s more than 630 nanometers in wavelength. The reason is simple: human eyes are more sensitive to red light than green light.
