Laser Pointer Safety

This project aims to develop and assess test setups for comparing uncertified laser pointers against a standard, and to evaluate filters for ensuring compliance. Corey Stevenson from UW-Madison leads the project, having obtained several laser pointers and initial data. More pointers are needed for a larger sample size, along with plans to test power and create household tests for unrated pointers.

  1. Laser Pointer Safety The goal of this project is to develop and evaluate test stands for comparing uncertified laser pointers with a standard and to evaluate filters to bring the laser pointers into compliance. Corey Stevenson, UW-Madison

  2. What Has Happened So Far? • Obtained a few laser pointers and some data: • 7 Laser Pointers- • 2 650 nm “red” laser pointers • 3 532 nm “green” laser pointers • 2 405 nm “blue” laser pointers • Used a ILX Lightwave Optical Power and Wavelength Meter to measure the power of the laser pointer along with the most prominent wavelength. • Tried to separate the IR and visible components using a hot mirror.

  3. Data So Far

  4. Things Needed • More laser pointers to get a larger sample size

  5. Plans • Obtaining more laser pointers • Testing the laser pointers’ power • Devising household tests to check unrated laser pointers
