The spectral region covered by an OPO system, using as a pumping source the radiation at 355 nm from a Nd

The spectral regions covered by different types of lasers .

The spectral response of three detector types, showing the spectral response both per photon and per Watt . The thin lines represent simple theoretical models, while the thicker lines suggest typical behavior for real detectors.

The spectral response y .

The spectral responses of the short-circuit photocurrent through an ITO polymer AI device, where the polymer layers are formed as layers of pure MEH-PPV. pure DHeO-CN-PPV. and a mixture of MEH-PPV and DHeO-CN-PPV see

The spectral sensitivity of the three sets of cone receptor cells

The spectral sensitivity of the xerographic gain of a 10 im single-layer aggregate photoreceptor measured with low-intensity continuous exposure incident on the positively charged surface at different fields.

The spectral shape of the carrier function

The spectral similarity in the p, region for a variety of H bonded carboxylic acids in GCU solution is apparent. Here the band widths are about 400 cm .

The Spectral Sketch Pad module of Virtual Waves allows for the creation of sounds graphically on a sketch pad area

The spectral variations seen from late M to L stars are illustrated. The figure is taken from the website www.stsci.edu inr ldwarfs originally published in

The spectral weight of the lower Hubbard . Note, the optimal doping corresponds to the half-filled copper-oxygen band which is reached for S 1 3.

The spectral width defines the size of the observed frequency window. Only within this window are the line frequencies correctly characterised.

The spectrochemical

The spectrochemical series. As a increases, shorter wavelengths of light must be absorbed to excite electrons. For reference, water is a weak-field ligand.

The spectrochemical series. As the crystal field strength of the ligand increases, the splitting energy of light must be absorbed to exdte electrons. Water is usuaily a weak-fieid ligand.

The spectrometer lock system monitors the dispersion mode signal of the solvent deuterium resonance. A shift of the resonance fiequency due to drift in the static field generates an error signal that indicates the magnitude and direction of the drift, enabling a feedback system to compensate this.
