A laser pointer or laser pen is a small portable device with a power source (usually a battery) and a laser emitting a very narrow coherent low-powered beam of visible light, intended to be used to highlight something of interest by illuminating it with a small bright spot of colored light.Safety Class: Visible laser pointers (400–700 nm) operating at less than 1 mW power are Class 2 or II, and visible laser pointers operating with 1–5 mW power are Class 3A or IIIa. Class 3B or IIIb lasers generate between 5mW and 500 mW, Class 4 or IV lasers generate more than 500 mW. Warning: Laser pointers if aimed at a person's eyes can cause temporary disturbances to vision. There is some evidence of rare minor permanent harm, but low-powered laser pointers are not seriously hazardous to health. They may be a major annoyance in some circumstances. A dot of light from a red laser pointer may be thought to be due to a laser gunsight, causing outrage and possible danger. When pointed at aircraft at night, laser pointers may dazzle and distract pilots.

Safety Considerations:

Laser pointers are effective tools when used properly. The following considerations should be observed when using laser pointers:

  • Never look directly into the laser beam and never point a laser beam at human eyes
  • Be careful on class 2 to class 4 lasers (Class 1 lasers are safe)
  • Do not aim the laser at airplane or reflective surfaces
  • Never view a laser pointer using an optical instrument, such as binocular or a microscope
  • Do not allow children to use laser pointers unless under the supervision of an adult
  • Do not open lasers more than 1min at a time which could reduction of service life
  • Remove the battery when not in use for a long time
