The first spectrometer was built
Lehrer created the first fully-automated spectrometer" to help more accurately measure spectral lines. New designs in optics, specifically prisms, enabled systematic observations of the solar spectrum. By passing a beam of light through a glass prism, he. With the first Abbe refractometer in 1874 and the Pulfrich refractor in 1895, Carl Zeiss Jena laid the foundation for materials analysis. Examples of important. Perhaps the first quantitative investigation that can be said to have a direct bearing on the science of spectroscopy would be the discovery of Snel's law of refraction in about 1621. In 1859, German chemist Robert Wilhelm Bunsen and physicist Gustav Robert Kirchhoff used it to identify materials that emit light when heated. A spectroscope transforms light into a spectrum.
