A spectroscope is a device which measures the spectrum of light. Early spectroscopes were simply a prism with graduations marking wavelengths. Modern spectroscopes generally use a diffraction grating, a movable slit and some kind of photodetector, all automated and controlled by a computer. It breaks up the white light given off by stars and separates in to its chracteristic colors.

Photosensors or photodetectors appear in several varieties: Photoresistors or Light Dependant Resistors (LDR) which change resistance when illuminated Photovoltaic cells or solar cells which produce a voltage and supply an electric current when illuminated Photodiodes which can operate in photovoltaic mode or photoconductive mode Phototubes containing a photocathode which emits...

The spectroscope was invented by Gustav Robert Georg Kirchhoff and Robert Wilhelm Bunsen. Gustav Robert Kirchhoff (March 12, 1824 - October 17, 1887), a German physicist who contributed to the fundamental understanding of electrical circuits, spectroscopy, and the emission of black-body radiation by heated objects. ... Robert Wilhelm Bunsen (31st March, 1811 – 16th August, 1899) was a German chemist. ...
In the original spectroscope design in the early 19th cent., light entered a slit and a collimating lens transformed the light into a thin beam of parallel rays.
It was based on the same principle as the spectroscope, but it had a camera in place of the telescope.
The Baseline eyes: the body's own spectroscopes: the author presents a discussion of the operation and optical complexities of the human eye.
