Imaging of plant cell walls by confocal Raman microscopy

Nature Protocols, 2012
Raman imaging of plant cell walls represents a nondestructive technique that can provide insights into chemical composition in context with structure at the micrometer level (

New Twists and Turns for Confocal Raman Microscopy

Frontiers in Optics, 2006
Confocal Raman microscopes usually reject elastically scattered light. This light, however, carries information about the target’s angular scattering properties. Imaging this rejected beam creates a multimodal microscope with chemical (Raman) and structural (elastic scatter) capabilities.

Materials analysis using confocal Raman microscopy

Macromolecular Symposia, 1999
AbstractThe recent development of Raman microscopes with high optical throughput and very sensitive CCD cameras has led to Raman spectroscopy again competing effectively with FTIR methods for materials analysis. Modern Raman instruments, designed to operate confocally without serious alignment or energy trade‐off problems, allow depth profiling of ...

Characterization of Ionomer Membranes with Confocal Raman Microscopy

ECS Meeting Abstracts, 2020
Ionomer membranes are crucial components of electrochemical energy systems such as fuel cells, electrolyzers, or redox-flow batteries. They need to meet demanding requirements for high-performance and long-term stable devices, and a targeted optimization of the membranes requires exact knowledge of parameters such as membrane thickness, ion exchange

Confocal fluorescence and Raman microscopy in industrial research

Colloid & Polymer Science, 1998
Modern chemical and pharmaceutical industrial research benefits from improved spectroscopic tools. New developments in confocal fluorescence and Raman microscopy lead to an increase in sensitivity, selectivity and speed of microscopic imaging and fluctuation analysis resulting in a better understanding of structure–property relationships essential for ...

Raman Instrumentation for Confocal Raman Microscopy

2010
Raman spectroscopy is a weak scattering technique in which typically less than one in a million excitation photons give rise to a single Raman photon. The situation is even more difficult in confocal Raman microscopy, as the detection volume is reduced by the small pinhole and thousands of spectra must be collected in a short period of time. Therefore,

Confocal Raman Microscopy of Streptococcus Sanguis and Mutans

Frontiers in Optics 2008/Laser Science XXIV/Plasmonics and Metamaterials/Optical Fabrication and Testing, 2008
Confocal Raman microscopy has been used to differentiate the spectra from biofilms of oral bacterial species Streptococcus sanguis and mutans. Improvements in processing algorithms allow this study to be performed using glass as a substrate.

Three-Dimensional Digital Confocal Raman Microscopy

Applied Spectroscopy, 1993
We describe an iterative image restoration technique which functions as digital confocal microscopy for Raman images. We deconvolute the lateral and axial components of the microscope point spread function from a series of optical sections, to generate a stack of well-resolved Raman images which describe the three-dimensional topology of a sample.

[Technique of confocal Raman microscopy on erythrocytes].

Guang pu xue yu guang pu fen xi = Guang pu, 2010
The technique of confocal Raman scanning microscopy (point scanning, line scanning and 2D scanning) and bright field imaging of living erythrocytes was investigated as a function of different scanning conditions at the excitation wavelength of 514 nm. The biological effect of the 514 nm laser radiation on the erythrocytes was also evaluated, so that a ...

Imaging theory of nonlinear Raman confocal microscopy

Journal of Modern Optics, 2008
A novel nonlinear Raman confocal microscopy utilizing Raman induced Kerr effect spectroscopy (RIKES) is presented in this paper. The imaging theory of RIKES confocal microscopy with Gaussian beam is derived. The imaging properties of RIKES confocal microscopy and the impact of different beam waist widths of Gaussian beam on the lateral and axial ...
