Mid-infrared Microspectroscopy of Difficult Samples Using Near-Field Photothermal Microspectroscopy

From: Spectroscopy | Date: February 1, 2004| Author: Hammiche, Azzedine; Bozec, Laurent; German, Matt J; Chalmers, John M; Et al | Copyright information

The authors discuss progress in near-field IR microspectroscopy using a photothermal probe and show how it can be applied to the spectroscopic characterization of real-world samples.

Despite recent advances in Fourier transform-infrared (FT-IR) microspectroscopy and micro-attenuated total reflectance (ATR), for many types of samples there remains a need for even higher spatial resolution, or for a nondestructive method of recording localized mid-IR spectra from as-received samples with...

Medical Device Technology ; Integrated optics explained Integrated optics was created in the 1970s. (1) It refers to the confinement and guiding of light in structures at least one of whose dimensions is smaller than the wavelength of light. A waveguide could, therefore, be a thin film of material with a high refractive index
Interplay between physics and statistics for modeling optical fiber bandwidth.
Technometrics ; In multimode optical fiber, the refractive index of the glass is varied radially in such a way that a light pulse propagates through multiple modes, or paths, as it travels. We investigate the prediction of fiber transmission capacity, specifically bandwidth, by using refractive index profiles of
