Measure wavelengths of light from 4000 Å to 7000 Å with accuracies of ±50 Å. -- The low price means that every student can have one of these spectroscopes, and the laser-produced diffraction grating (which produces excellent results) means that every student will want one. -- This hand-held spectroscope is one of our best-selling products partly because it allows students to analyze light in both emission and absorption spectra. The scale is 37 mm long. Developed by Werner Schultz. -- Includes: unbreakable plastic case, laboratory suggestions and instructions. |
