Multispectral imaging systems are used by the food industry, the pharmaceutical industry, and in medical, biology, and chemistry labs for analysis and quality control. Types of multispectral imaging include NIR (near infrared), which can provide a quick and accurate analysis of samples within the 700–2500 nm wavelength range, and Raman, which measures the scattering of near infrared, visible, or near ultraviolet light. In both cases, the photons that are emitted and absorbed by the sample allow identification of specific molecules.
Considerations for purchasing a Multispectral Imaging System
Sensitivity, specificity, and resolution of images can vary between chemical imaging systems. Another feature to be aware of is what type of imaging the system is capable of and whether other types of imaging can be integrated into the system.

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.
