My laser won't cut black electrical tape.

The ability to cut tape varies with different types and colors of tape. Try the following suggestions:

  1. Try using brand new batteries. Do not use AA or AAA rechargeable batteries
  2. Try marking the tape with a sharpie or other black marker if you are using a light colored tape.
  3. Try putting some weight on it so that it stretches.
  4. Keep you hands steady or use a tripod to ensure a steady beam.
  5. Shorten the distance between the laser and the tape.
  6. Use the focal lens from the Expanded Lens Kit.

Lasers with an output power of 95mW and above should be able to cut electrical tape.
