When the laser pen is in formal work, it always requires a certain operating environment. Typically, it is acceptable for operating temperatures from 10 degrees Celsius to 40 degrees Celsius. Some special laser pointers may work at operating temperatures in the 0-40 degrees Celsius or lower operating temperature range.

Preheating the laser tube is important when the operating temperature of the laser pointer is much lower than expected. In particular, the head of the laser pointer should be preheated in the jacket or hand. If the laser pointer is activated in an indoor working environment, it will return to a formal or near formal working environment.

In the winter when the working environment is low, the laser beam emission is always very weak at the beginning of the startup, dim and not bright. After continuous pointing (usually after 10 seconds), the laser beam brightness returns to normal. When the operating temperature is quite low, the laser operator should preheat the laser pointer. Low temperatures can seriously affect the normal operation of the laser pointer.

Heavy fog sometimes occurs in winter, and laser operators should pay special attention to the operating environment. The user should prevent atomized dust from adhering to the lens of the laser pointer, thereby affecting the quality of the laser spot, which indirectly affects the thermal efficiency of the beam.

Especially below zero temperature, the light of the laser pointer may appear weak or even impossible to start. In the winter, laser users should pay special attention to the surrounding environment to ensure the official operation of the laser pointer.

Therefore, be sure to protect the laser.
