Figure 3.3 Near-field transmission spectra and images of a single gold nanorod (length 510nm, diameter 20nm). The two transmission spectra were obtained at positions 1 and 2 indicated in the inset. Each image was obtained at the resonance peak wavelength. (Reproduced with permission from Royal Society of Chemist [10]).

Figure 6.4 Plotting absorbance versus wavelength at several levels of pH for a BCG optical sensor shows that the alkaline form of the indicator absorbs at about 620 nm and the acidic form absorbs at about 450 nm. At about 550 nm both forms have the same molar absorptivity (isobestic wavelength). (Reproduced from LASERFOCUSWORLD.COM.)...

The temperature tuning coefficient of TeOa is 0.025 nm/°C, so it is clear that in order to combat the effects of thermal heating of the crystal due to incident optical and aconstic power, as well as environmental considerations, a good level of thermal control is needed. This can be in the form of a thermo-electrically cooled enclosure. This will deal to a certain extent with the need to achieve analyzer wavelength repeatability. However, it does not address the issue of wavelength reproducibility between AOTF modnles, which impacts the transportability of calibrations and datasets between analyzers. [Pg.126]

Wavelength reproducibility can be simply checked by an overlay of repetitively recorded line emitter or holmium perchlorate solution spectra. Since wavelength reproducibility is especially important in kinetic investigations, a chemical reaction can also be used as standard, for which the... [Pg.440]

Spectrofluorimeter. Preferably capable of synchronous scanning, with wavelength reproducibility of excitation and emission monochromators +2nm or better typical monochromator gratings of 6001ines/nm blazed at 300 nm or better, spectral resolution with bandpass of 2.5 nm or less, maximum bandpass of 10 nm and a response of S-20 or S-5 on the photomultiplier tube.

A second advantage of Fourier transform instruments is their extremely high resolving power and wavelength reproducibility that make possible the analysis of complex spectra in which the sheer number of lines and spectral overlap make the determination of individual spectral features difficult. Figure 7-40. which is papt of an emission spectrum for a steel, illustrates this advantage. The spectrum, which extends from only 299.85 to 300.75 nm, contains thirteen well-separated lines of three elements. The wavelength resolution (AA/A) for the closest pair of lines is about 6 ppm.
