3 Laser Pointers Set - Red Green Blue

A highly affordable set of 3 laser pointers, perfect for performing experiments involving refraction in the classroom or at home.  Light refracts differenly depending on the wavelength of the light.  As such, this kit includes a red, green, and blue laser pointer, each of a different wavelength, in order to give a sample of the refractive properties of light at different wavelengths along the whole spectrum of visible light.  Shine them through a prism or a diffraction grating and observe the differences!  Makes for a great entry-level science fair project or fun classroom activity.

Note: Each laser pointer requires 2 AAA batteries; NOT included

Laser Properties:

Green: 532nm +/- 10

Blue: 405nm +/- 10

Red: 650nm +/- 10

Features:

• Highly affordable set
• 3 laser pointers included, set to different wavelengths
• Shows the effect of wavelength on refraction
• Excellent for classroom demonstrations or science fair projects

  Just what I wanted
Michael from Frisco, TX USA
Some reviewers have noted that the 'blue' pointer seems a bit faint. It's actually a violet / near ultraviolet laser, and it will definitely light up things that fluoresce under long-wave UV.

  Ok

Ok for inexpensive laser's. Red and green were fine but blue was a little week.
