How to Make a Homemade Laser Pointer

Laser pointers may be inexpensive to buy, but there’s fun in making your own. A homemade laser pointer will work as well as one from a store and give you a sense of accomplishment every time you see the laser beam. The process of making a homemade laser is not complicated and just requires buying a laser module and an LED flashlight.

Step

Put a towel down on a table.

Step

Remove the battery cap and batteries from the LED flashlight. Put the battery cap and batteries down on the towel.

Step

Unscrew the reflector from the front of the LED flashlight. Remove the plastic lens inside of the reflector and discard it. Put the reflector down on the cloth.

Step

Pull out the LED bulb from the LED flashlight using the needle nosed pliers. Discard the bulb. Place the LED flashlight down on the cloth.

Step

Twist the AixiZ laser housing between your hands to separate the front and back casings from each other. Discard the front casing of the AixiZ laser housing.

Step

Heat up the soldering iron. Take the back section of the AixiZ laser housing that has the exposed laser diode now showing and place it down on the towel.

Step

Solder a conductive pin each to the positive and to the negative contacts on the body of the laser diode. Let the solder cool.

Step

Insert the back half of the AixiZ laser housing, conductive pins first, into the LED flashlight. Apply a thin layer of bonding glue to hold the AixiZ laser housing to the inside of the LED flashlight. Let the bonding glue dry.

Step

Screw the reflector back onto the LED flashlight. Put the batteries back into the LED flashlight and screw on the battery cap.

Step

Aim the LED flashlight that has now been turned into a homemade laser pointer at a wall across the street. Press the button to project the laser light onto the wall.
