Laser light sources don’t just last longer, their performance is also more consistent over time. Where lamps will inevitably dim after a while, laser-based systems offer steadier brightness that decreases at a much slower pace.

What can damage a laser diode?

electrostatic discharge
Electronics Laser diodes are susceptible to damage from electrostatic discharge. They are most vulnerable in the interval between when they are unpacked and when they are secured within the system. Use grounded wrist straps and grounded anti-static mats at all times when handling a laser diode.

What are the dangers of laser pointers?

The greater a laser pointer’s output power, the more likely it will cause serious eye injuries, burn skin and temporarily — or permanently — impair the vision of pilots, drivers or bystanders.

Do laser pointers have output power?

However, the output power of laser pointers is not immediately apparent to the user. Laser pointers often lack the required labeling or are mislabeled, and definitive testing of individual pointers is beyond the reach of the average consumer.
