A laser pointer uses a small lens to focus the laser light as it exits the barrel of the pointer. A dirty or cracked lens inhibits the laser light and renders the laser pointer useless. Replacing the lens in a laser pointer can be done by the casual user because it doesn't require replacing any electronic parts. The process requires a new lens from a similar laser pointer, and the entire procedure can be done in as one hour.
Instructions
1. Put a clean cloth down a work surface.
Take the replacement laser pointer and hold it with one hand at each end. Twist the laser pointer to break the glue holding the center seam between the two halvesof the replacement laser pointer.
2. Separate the two halves of the replacement laser pointer. Discard the half with the laser mechanism. Put the other half down on the clean cloth.
3. Insert the cotton swab at the front end of the half of the replacement laser pointer that is now on the clean cloth. Push the lens from inside of the half out and onto the clean cloth. Discard the half of the replacement laser pointer that no longer has the lens in it.
4. Take the laser pointer that is to have a new lens and hold it with one hand at each end. Twist the laser pointer until the glue at the middle of the two halfs comes loose.
Separate the two halves. Put the half with the lens in it down on the clean cloth.
5. Unscrew the battery cap from the half of the laser pointer that has the exposed laser mechanism now showing. Remove the batteries, and put them and the battery cap aside. Place the half of the laser pointer with the exposed laser mechanism down on the clean cloth.
6. Pick back up the half of the laser pointer, which has the lens inside it. Poke out the lens using a cotton swab. Discard the lens.
7. Carefully pick up the replacement lens that is on the clean cloth. Insert it into the half of the laser pointer that had the lens inside of it. Move the lens into position in the half of the laser pointer using a cotton swab.
8. Place the two halves of the laser pointer back together. Put a thin layer of bonding glue on the seam where the two halves come together. Hold the two halves together until the glue sets.
9. Put the batteries back into the laser pointer. Screw on the battery cap.
Aim the laser pointer at a wall that is far away and press the button. Watch the laser light emerge.
