Visible and ultraviolet absorption spectra are measured in an absorption spectrometer. The source gives out intense visible light or ultraviolet radiation. The wavelengths can be selected with a glass prism for visible light and with a quartz prism or a diffraction grating for ultraviolet radiation (which is absorbed by glass). A typical absorption spectrum, that of... 

Figure 10. Reflectivity for the geometry consisting of an SF14 glass prism, 50 nm thick gold layer, and a dielectric, as a function of the angle of incidence for two different refractive indices of the dielectric wavelength = 682 nm.

Figure 4. Reflectivity in the Kretschmarm geometry of ATR consisting of an SF14 glass prism (refractive index - 1.65), a gold layer (thickness - 50 nm), and a low refractive index dielectric medium (refractive index - 1.32), and wavelength - 800 nm.

The immune biosensor analysis was carried out in the SPR-4 M device produced by the Institute of Physics of Semiconductors of the Ukrainian National Academy of Sciences. SPR spectroscopy was carried out in the Kretschmann configuration using He-Ne laser ( i=632.8 nm), goniometer (G-5 M), glass prism (the angle at the basis 68°) and photodiode (FD 263). The optical contact between the prism and the metallic layer was achieved by the application of polyphenyl ether (refractive index n= 1.62). 

For the study of the first overtones of the O—H, N—H, and C—H bonds, situated in the range from 8000 to 5500 cm-1 we used a double beam recording autocollimating spectrophotometer with glass prisms, similar to that described before [19, 22] and constructed in the laboratory. The recording was photographic. The spectral slit width was 15 cm-1 at 7000 cm-1. 

Towards light, carbon disulphide possesses high refractive and dispersive powers, and in these properties is exceeded only by methylene iodide, bromonaphthalene and phenyl mustard oil. On this account it is used for filling hollow glass prisms for the production of spectra.4... 

An atom absorbs or emits only particular frequencies of light. White light bends into a glass prism and separates into a rainbow of colors. In which of these two scenarios does the electromagnetic radiation... 

SPECTRO INSTRUMENTS. Spectro is used as a prefix for a wide assortment of analytical instruments. Spectro is derived from spectrum, which originally referred to the component colors that make up visible light, the so-called rainbow colors of violet, indigo, blue, green, yellow, orange, and red. A very simple device made up of a glass prism to break up sunlight into color bands is referred to as a spectroscope. Much more sophisticated instruments are available for manual manipulation and observation, which still rely on this basic, simple principle these are termed visual spectroscopes, and the field is called visual spectroscopy.

When the interface between a thin ( 50nm) film of free-electron metal (e.g., Au, Ag, or Al) and a glass prism is irradiated with a TM polarized coherent light, correlated motion of free electrons in the metal leads to the formation of oscillating charge at the metal/glass interface (Fig. 9.16)... 

It is important to realize that for the plasmon resonance to occur the condition of two matching plasmons at the opposite interfaces of the thin metal must be met. In other words there must be a dielectric/metal interface at which an evanescent field is created. In the Kretschmann geometry that interface is created by having the metal coated on the glass prism. Likewise, the SPR condition can also be realized in a fiberoptic format with a thin metal layer deposited on a flattened single-mode optical...
