How to Take Apart a Laser Pointer


A laser pointer is a pen-like instrument that projects an optical beam. The device is commonly used in presentations to highlight points of interest. If you are having problems with your laser pointer, you can open up the unit in order to diagnose problems or replace internal components. The process doesn't take a whole lot of time, but since the device is so small it will require some concentration.

Things You'll Need

  • Paperclip
  • Turn off your laser pointer and unscrew the unit. On some pointers the unit will unscrew at the middle, and on some units the end of the pointer will unscrew or pop off to expose the internal components.

  • Look into the compartment of the pointer and you will see a coiled metal diode. Use the end of a paperclip or other thin tool to pull the diode from the unit, disconnecting it from the motherboard in the process.

  • Use your tool to remove the thin motherboard from the compartment. Unplug the cables that run from the motherboard to the lens of the laser pointer. On some units these wires will be soldered to the board and will require wire clippers to cut them.

  • Unscrew the lens from the front of the pointer and set it aside.
