More educational than a Pink Floyd concert and more fun than a laser light show, these diffraction grating glasses separate light from any source into its spectral components. Study and analyze the spectra seen through these holographic lenses or just see what colors lie within the lighting in your home. Glasses produce 13,500 lines per inch.
