2. Spectroscopy - Wikipedia

   en.wikipedia.org/wiki/Spectroscopy

   Spectroscopy, primarily in the electromagnetic spectrum, is a fundamental exploratory tool in the fields of astronomy, chemistry, materials science, and physics, allowing the composition, physical structure and electronic structure of matter to be investigated at the atomic, molecular and macro scale, and over astronomical distances.

3. Chemiluminescence - Wikipedia

   en.wikipedia.org/wiki/Chemiluminescence

   Chemiluminescence (also chemoluminescence) is the emission of light (luminescence) as the result of a chemical reaction, i.e. a chemical reaction results in a flash or glow of light. A standard example of chemiluminescence in the laboratory setting is the luminol test. Here, blood is indicated by luminescence upon contact with iron in hemoglobin.

4. Dichroism - Wikipedia

   en.wikipedia.org/wiki/Dichroism

   An example is the dichroic prism, used in some camcorders, which uses several coatings to split light into red, green and blue components for recording on separate CCD arrays, however it is now more common to have a Bayer filter to filter individual pixels on a single CCD array. This kind of dichroic device does not usually depend on the ...

5. Optical spectrometer - Wikipedia

   en.wikipedia.org/wiki/Optical_spectrometer

   The wavelength of light is then selected by the slit on the upper right corner. An optical spectrometer (spectrophotometer, spectrograph or spectroscope) is an instrument used to measure properties of light over a specific portion of the electromagnetic spectrum, typically used in spectroscopic analysis to identify materials. [1]

6. History of spectroscopy - Wikipedia

   en.wikipedia.org/wiki/History_of_spectroscopy

   History of spectroscopy. Light separated into a spectrum by refraction through glass prism. Colour dispersion angles exaggerated for visualisation. Modern spectroscopy in the Western world started in the 17th century. New designs in optics, specifically prisms, enabled systematic observations of the solar spectrum.

7. Spectrometer - Wikipedia

   en.wikipedia.org/wiki/Spectrometer

   Spectrometer is a broad term often used to describe instruments that measure a continuous variable of a phenomenon where the spectral components are somehow mixed. In visible light a spectrometer can separate white light and measure individual narrow bands of color, called a spectrum. A mass spectrometer measures the spectrum of the masses of ...

8. Prism (optics) - Wikipedia

   en.wikipedia.org/wiki/Prism_(optics)

   A familiar dispersive prism. An optical prism is a transparent optical element with flat, polished surfaces that are designed to refract light. At least one surface must be angled — elements with two parallel surfaces are not prisms. The most familiar type of optical prism is the triangular prism, which has a triangular base and rectangular ...

9. Electromagnetic spectrum - Wikipedia

   en.wikipedia.org/wiki/Electromagnetic_spectrum

   Electromagnetic spectrum. The electromagnetic spectrum is the full range of electromagnetic radiation, organized by frequency or wavelength. The spectrum is divided into separate bands, with different names for the electromagnetic waves within each band. From low to high frequency these are: radio waves, microwaves, infrared, visible light ...
