Laser Maintenance

For DPSS Lasers:

1. Avoid direct eye exposure to the laser beam. Note that a reflected laser beam can be just as powerful as directly coming from the laser unit itself.

2. Keep the laser free from dust or other contaminates that could cloud or dirty the laser lens or crystal array.

3. We recommend using the  laser goggles . A direct exposure to the laser beam may cause severe and irreparable eye damage.    

4. Operate your laser only within the specified temperature range of 10°C to 35°C.

5. Do not take apart, modify or dismantle the laser or operate it under abnormal current load.


For  Laser Pens:

Every laser pointer and portable laser from Ultralasers should last you for at least 5000 hours if you look after it properly.In practical terms, that means if you use your laser for 3 hours a day every day, your laser will last you for over 4.5 years. Here are some tips on looking after your laser to make sure it does last for over 5000 hours.

When not in use, do not keep the batteries in your laser.

If the batteries are left in your laser pointer or portable laser, they may cause corrosion of the battery terminals and other problems.

Always keep the lens covered when your laser is not in use.

For portable lasers, this means keeping the lens shutter closed. For laser pointers, you can cover the lens with tape or a similar weak adhesive.Just be careful the tape will come of the lens cover cleanly.


Your laser should be stored in a dry place with humidity of no more than 45% and temperature should ideally be no lower than 0 Celsius and no higher than 50 Celsius.

Handle your lasers gently.

These lasers are sophisticated electronic devices with delicate optics that should always be treated gently, never roughly.

The lens are very easy to be damaged or scratched when cleaning them, so great care should always be used.

Ideally you should get a professional such a camera repair/service person to clean your lens for you.
