2. It is recommended not to keep the laser on for more than 60 seconds, otherwise it will affect the use of the laser due to overheating;
4. If you find that the brightness of the laser beam is significantly reduced, please pay attention to charging. Charging when there is no electricity will cause the built-in lithium battery to fail to store electricity;
◆ Teachers, professors ◆————Used for classroom teaching, so that you can easily "point to the blackboard" from a hundred meters away. It is the right assistant of teachers! The laser power for this purpose is generally less than 20mw.
◆Business people, white-collar workers ◆------Used for product demonstrations and lectures. The green laser gives people a refreshing feeling. The laser power for this purpose is generally higher than 20mw.
◆ Conference speaker, museum/exhibition venue/scenic spot commentator ◆———— Facing the big, high and far goal of "hard to reach". The laser power for this purpose is generally between 20mw and 50mw.
◆ Field travelers, explorers ◆--Used for field lighting, indicating distant targets and sending distress signals. The characteristics of the new product are: it does not affect product performance in extremely cold and hot environments; it has the functions of waterproof, moisture-proof, sweat-absorbing, water-absorbing, and abrasion resistance, which is especially suitable for outdoor use. The laser power for this purpose is generally 30mw-150mw.
◆ For enthusiasts of starry sky observation ◆－－－It is used to refer to the stars. The emitted laser will draw a beautiful “green light” in the night sky, reaching the target airspace, which is very spectacular. The laser power for this purpose is generally 50mw-200mw, the greater the power, the farther the range, the brighter the light.
◆ Relevant personnel in mining farms and construction sites ◆---used to accurately indicate the targets of buildings or mining farms at a long distance to avoid approaching dangerous areas. The laser power for this purpose is generally higher than 30mw.
