When Was the Spectrometer Invented?

Although the apparatus Isaac Newton used in his work on the spectrum of light can be considered a crude spectroscope, it is generally recognized that the spectroscope was invented by Gustav Kirchhoff and Robert Bunsen

Robert Bunsen
Robert Wilhelm Eberhard Bunsen (German: [ˈbʊnzən]; 30 March 1811 – 16 August 1899) was a German chemist. He investigated emission spectra of heated elements, and discovered caesium (in 1860) and rubidium (in 1861) with the physicist Gustav Kirchhoff.

around 1860.

When was spectrophotometer invented?

The spectrophotometer, a key instrument today in biomedical laboratories, was invented in 1939 by the American chemist Arnold O. Beckman (1900-2004).

Why is a spectrometer so called?

Optical spectrometers (often simply called "spectrometers"), in particular, show the intensity of light as a function of wavelength or of frequency. The different wavelengths of light are separated by refraction in a prism or by diffraction by a diffraction grating.
