DXR2xi Raman Microscope

Raman spectroscopy is a powerful analytical technique used in various fields to investigate molecular vibrations, crystal structures, and chemical compositions. Its applications are diverse and include:

Material Science:
Quality Control: Raman spectroscopy can be used to assess the quality and composition of materials, such as polymers, semiconductors, and ceramics.

Chemistry:
Chemical Analysis: Raman spectroscopy is used for chemical identification, quantification, and monitoring chemical reactions in real-time.
Molecular Vibrations: It provides insights into molecular vibrations, making it valuable for studying molecular conformations and isomerism.

Biomedical Science:
Cellular and Tissue Analysis: Raman spectroscopy can identify and characterize biological molecules in cells and tissues, aiding in disease diagnosis and tissue engineering.
Drug Interaction: It helps study drug interactions within biological systems and monitor drug delivery mechanisms. 

Environmental Science:
Pollution Monitoring: Raman spectroscopy can be used to detect and quantify pollutants in air, water, and soil samples. 

Food Science:
Food Analysis: Raman spectroscopy is applied for the analysis of food components, such as fats, proteins, and carbohydrates, as well as for detecting adulterants and contaminants.

Nanotechnology:
Nanoparticle Characterization: Raman spectroscopy helps in characterizing nanoparticles, including their size, composition, and surface properties.
Graphene Analysis: It's used to study graphene and other 2D materials.

Features

The system (can be operated at two wavelengths: 532 nm or 785 nm) consist of:

• one or more single coloured light sources (lasers)
• lenses (both to focus the light onto the sample and to collect the scattered light)
• filters (to purify the reflected and scattered light so that only the Raman light is collected)
• a means of splitting the light into its constituent colours (normally a diffraction grating or prism)
• a very sensitive detector (to detect the weak light)
• a device such as a computer to control the whole system, display the spectrum and enable this information to be analysed

Raman scattering offers significant advantages for the investigation of materials over other analytical techniques, such as x-raying them or seeing how they absorb light (e.g. infrared absorption or ultraviolet absorption).
