The 6.0 laser module has a laser head with a diameter of 0.6mm and positive and negative terminals. It operates at a voltage of 3.3V to 5V. The laser beam forms a faint red line only in fog or other media, while under normal conditions, a red dot is visible. The body is made of copper. It is primarily used in laser toys, light-emitting tops, various levels, and ground line instruments. Special caution: Do not point it at human eyes.
