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.

Spectroscopes are expensive, but they allow you to analyze light to tell, for instance, the composition of a star's atmosphere or the gases in a fluorescent bulb.
Your purpose is to make a very simple spectroscope using a CD as a reflection diffraction grating and investigate various light sources.
Once you have made your spectroscope, try it out with some bright light sources such as a fluorescent light, a bright computer or TV screen.

 Bunsen Spectroscope
The basic features of the spectroscope (or spectrometer) include a slit and collimator to produce a parallel beam of light which then falls on the dispersive element (a prism).
In the Bunsen spectroscope the relationships of the telescope and collimator are fixed at angles appropriate to viewing the visible spectrum through a prism.
This example is a student instrument for the determination and analysis of spectra using either a prism or grating.

 grating spectroscope from Armchair World
Spectroscopes have many uses: scientists use spectroscopes to study the chemical composition of stars, metallurgists use spectroscopes to determine the composition of mineral specimens, and chemists use spectroscopes to determine the constituents of chemical compounds.
Our spectroscope kit is made of thick, silver-colored cover stock and comes with a pre-cut slit and a pre-mounted diffraction grating embossed with 23,000 lines per inch.
To assemble the spectroscope, simply cut it out, fold it up, glue it together and you're ready to observe the visible spectrum.

The spectroscope will separate light into its component colors by diffraction, deflecting the longer wavelength (red) light more than the shorter wavelength (blue/violet) light.
With the spectroscope you can see which wavelengths are present, and how bright each is. There is a lot to be learned from the precise wavelength of light emitted or absorbed by an object, and each wavelength of light has a particular color, so scientists tend to consider color to be equivalent to wavelength.
Note the arrows on the sides of the spectroscope that show the directions to the light source, and to look.

 AA! - Astrology Alive! The Significance of Asteroids. J. Schwartz
These interactive vibrational forces draw energies into connection.
Perhaps the physical properties of the asteroid: its name, apparent shape, chemical composition, spectroscope, orbit carries a vibrational frequency, or sound, which the discoverer unconsciously connects with a name.

 "Maxwell, Molecules, and Evolution" by Charles Petzold
Much of the lecture focuses on properties of molecules and atoms, particularly as they relate to the diffusion of gases.
Towards the end of the lecture, Maxwell discusses how the spectroscope has shown molecules of a particular type (for example, hydrogen) to be exactly the same regardless whether they are found on earth or revealed in the light from distant stars:
Each molecule, therefore, throughout the universe bears impressed on it the stamp of a metric system as distinctly as does the metre of the Archives at Paris, or the double royal cubit of the Temple of Karnac.
