How To Use A Laser Pointer (and more)

SO WHAT IS A LASER POINTER?

A laser pointer or laser pen is a small handheld device with a power source (usually a battery) and a laser diode emitting a very narrow coherent low-powered laser beam of visible light, intended to be used to highlight something of interest by illuminating it with a small bright spot of colored light. Power is restricted in most jurisdictions not to exceed 5 mW.   The first laser pointer was built in 1960 by Hughes Aircraft.  The first laser pointers were released in the early 1980s.

HOW TO USE A LASER POINTER…

If your attorney has a need to point out relevant issues in the courtroom either during trial or during their closing argument, they may have a need for using a laser pointer.  Here are some detailed and complete instructions for using a laser pointer:

  1. Find a test area on the floor or on the wall to test the laser pointer.  Do NOT point the laser pointer at a person or aircraft.
  2. Press the button on the laser pointer to activate the laser.
  3. Locate the laser dot in the direction you are pointing.
  4. Draw attention to the subject matter with the laser dot by circling objects instead of pointing.
  5. Release the button to turn off the laser.

NOTES: 

  • Do not use a laser pointer on a flat screen monitor.  Most monitors will not reflect the laser dot thus making it ineffective.
  • Be aware that the laser beam doesn’t end.  Some beams can travel up to 22 miles.

WHAT’S THE DIFFERENCE BETWEEN A RED OR GREEN LASER POINTER?  DOES IT MATTER?

Green can be used inside or out, but green is much more visible outside.  But for courtroom purposes it really doesn’t matter; however, studies show that our eyes see green better than any other colors.  In my experience, people are generally more at ease looking at a green laser dot which is helpful if you are presenting something to a jury.
