The development history of cross hair laser pointer

Because it is difficult to cool the temperature-sensitive solid crystal inside the pointer. According to the manufacturer, the higher the output of a powerful laser pointer, the more violent the temperature rise, so if it is not used, it will cause malfunctions to avoid storing heat, such as a single use for a short period of time. be careful. On the contrary, if the temperature is too low, the laser module may not light up normally. Please note that there is no clear division from "purple" to "indigo", but it is infinite, because it has a continuous spectrum, like purple indigo, purple indigo...indigo purple. This means that there is a gradual color. The laser system will burn your skin. The likelihood of burns and the degree of burns depend on the wavelength and output. Some laser systems form part of large-scale equipment, so operators and people around the laser should be fully considered when operating.
