		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.

		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.

	Simple Spectroscope
		Description: A basic hand-held spectroscope is made from a diffraction grating and a paper tube.
		Spectrographs are spectroscopes that provide a record, photographic or digital, of the spectrum observed.
		One sheet is usually enough for every student in a class to have a piece of grating to build his or her own spectroscope.

	Virtual Spectroscope
		By using a spectroscope, scientist can read the absorption and emission patterns of different substances in a star's light spectrum and determine its make-up.
		The program generates a visual representation, or "spectroscope view," of a spectrum simultaneously with a graphical representation showing the spectral intensity vs. wavelength.
		Virtual Spectroscope banishes boring, static examples and offers a colorful, visual explanation that enhances the study of spectra in astronomy, biology, chemistry, earth science, physics, and physical sciences.

	Spectroscope
		Spectroscopes can help students build a deeper understanding of light and of wave behavior in general.
		To use the spectroscope, either tape or hold the diffraction grating slide over the viewing hole in the box.
		The stripes of colored light that you see in the spectroscope are often called 'bands'.

	Chapter 7: Light and Optics
		A spectroscope is a device that lets us find out what things are made of.
		The spectroscope spreads out the colors of the light, and we can identify the elements by the bright lines we see in the spectroscope.
		I replaced the grating in the cereal box spectroscope with one of these high resolution gratings, and you can now clearly see several lines in the yellow and orange that were smeared together in the earlier version.

	Prism Spectroscope (Site not responding. Last check: 2007-11-07)
		In addition to the prism, the other essential elements of a prism spectroscope are a narrow slit, a collimator, and a telescope.
		The narrow slit is the gate through which the light enters the spectroscope.
		If some wave lengths are missing in the light entering the spectroscope, the spectrum will not be continuous.

	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.

	Student 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 or grating).
		It could be used for the determination and analysis of spectra using either a prism or grating.
		It could also be used in the measurement of angles between prism faces, the determination of angles of refraction and reflection etc. In another common type of instrument, the Bunsen Spectroscope, there is no graduated circle, instead measurements are made relative to a projected scale.

	"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.
