How to perform the laser pointer operation correctly?
When the Laser pointer is in formal work, it always requires a certain operating environment. Generally, a working temperature of 10 degrees Celsius to 40 degrees Celsius is acceptable. Some special laser pointers may work in the operating temperature range of 0-40 degrees Celsius or lower. When the working temperature of the laser pointer is much lower than expected, it is important to preheat the laser tube. Especially the head of the laser pointer should be warmed up on the jacket or hand. If the laser pointer is activated in an indoor working environment, it will return to a formal or nearly formal working environment.
