ESAW Grating Spectroscope (LO-6115)

A diffraction grating spectroscope for viewing visible lines and absorption spectra. The spectrum is visible, superimposed on a scale, which gives the approximate wavelengths. The high-resolution diffraction grating replica used produces an extremely bright spectrum. The complete body of unbreakable molded plastic and can easily be held in the hand. The construction eliminates internal reflections to provide the sharpest, clearest spectrum possible.
