People have examinations, and so do laser equipment. High temperature is a necessary test for laser equipment in summer.

Continuous online high temperature weather makes the temperature in the production workshop easily exceed 40 ℃. If it is not done well, condensed water will easily appear inside the laser, causing damage to internal electrical components or modules.

So, how to prepare for the exam? It is suggested to build an air-conditioned room for laser equipment and set the temperature between 22 and 26 ℃. Every day after work, the air conditioner should be kept on and dehumidification function should be set.
