(Latin: to see, seeing; to look at, looking at; sight, to appear, appearing; to behold, to examine, examining)

spectropolarimeter
A device that gathers information on the polarization state of individual chemical reactions from a star seen as lines in the star's spectrum.
spectroradiometer
1. An instrument for determining the radiant-energy distribution in a spectrum, combining the functions of a spectroscope with those of a radiometer.
2. A digital light meter that measures spectral wavelength color and reflectance of UV to the infrared, lux color, etc.
spectroscope
An instrument that disperses light into its spectrum, magnifies it, and displays it for observation.
spectroscopic
A reference to or using a spectroscope.
spectroscopic ellipsometry
1. A spectroscopic ellipsometer allows for the accurate characterization of a range of properties including the layer thickness, optical constants, composition, crystallinity anisotropy, and uniformity.
2. Ellipsometry which uses more than one wavelength and allows variation of an angle of incidence; measures not only film thickness, but also provides information on select chemical/physical characteristics of the film(s); very useful in process monitoring and diagnostic.
3. Ellipsometry which uses more than one wavelength and allows variation of an angle of incidence; measures not only film thickness, but also provides information on select chemical/physical characteristics of the film(s); very useful in process monitoring and diagnostic.

Ellipsometry is the most common way of measuring thickness of thin films; based on the detection of phase shift of plane polarized incident light beam during reflection from the surface.

Thickness determines ranging from a few angstroms to tens of microns are possible for single layers and complex multilayer stacks.

spectrum
speculate (verb), speculates; speculated; speculating
1. To form a thought or theory on the basis of incomplete facts or information and to think over possibilities: People are speculating on the probable causes for the unexpected resignation of the mayor this morning.
2. To engage in or to take risks with financial transactions; such as, commodity trading that has an element of risk; especially, in the short term, with the hope of making a profit: Marla's uncle used to be wealthy; but when he speculated on the wrong stock, he lost most of his money.
3. To consider or to discuss why something has happened or what might happen: Irwin was speculating on whether his stomach ache was caused by the three pieces of chocolate cake that he ate or if he caught a flu bug on the subway when he was going home.
To buy or to sell a commodity in order to gain a profit.
