In Raman microscopy, also called confocal Raman microscopy, an optical microscope and a Raman spectrometer are combined into one instrument in order to provide high resolution images of small samples. This high resolution imaging has applications that include materials science, earth science, cell biology, medicine, cosmetics, and art analysis.
A Raman microscope consists of a basic optical microscope, a Raman spectrometer, a laser, a light source, and a detector such as a CCD camera. The optical microscope uses light to magnify and identify samples while the Raman spectrometer scatters light and measures the excitation vibration. When selecting a microscope, it is important to consider the qualities of each of the microscope's components and their optimal configuration for a particular application.

| Description | ParticleScout is an advanced particle analysis tool for witec360 Raman microscopes that finds, classifies and identifies microparticles over even large sample areas.
User-defined categorization of particles by shape and size offers access to wide-ranging properties, and the results of the ParticleScout is an advanced particle analysis tool for witec360 Raman microscopes that finds, classifies and identifies microparticles over even large sample areas.
User-defined categorization of particles by shape and size offers access to wide-ranging properties, and the results of the measurement are then presented in a report that provides a comprehensive description of the sample.
ParticleScout features the most flexible and useful sample survey capabilities available.
- White-light Microscopy: Bright field/dark field, transmission/reflection.
-
Image Stitching: Scans of many sample areas can be combined into one measurement for a large-area overview of widely distributed particles.
-
Focus Stacking: This unique capability dramatically increases the depth of focus for sharp and defined particle imaging.
-
Integration time optimisation – reduces measurement time and minimizes the effects of fluorescence.
-
Vignetting correction – ensures uniform brightness throughout the image plane.
-
Smart zoom – displays particle information dynamically depending on viewed area.
-
Sample area targeting – allows the selection of multiple regions of interest for each investigation.
-
Dark-field, bright-field, epifluorescence and transmission sample illumination – provides the best option for each type of particle.
-
Round sample wedge sectioning – allows the selection of an area for data acquisition, typically on a filter, that can be extrapolated to represent the whole.
-
Smart separation of particles – differentiates materials in densely packed, heterogeneous samples.
-
• Quantitative report formatting – presents data using table, bar graph histogram and pie chart templates for ease and clarity.
