● Other capabilities - Low wavenumber measurements (down to 15 cm-1 with 532 nm laser), polarization study with 532 nm laser, remote probe fibre coupling with 532 nm laser.
Useful for
● Material Science: used to study properties of materials, including their crystallinity, phase composition, and stress/strain states.
● Life Sciences: helps analyze biological samples such as proteins, nucleic acids, and lipids, revealing their molecular structures and distributions.
● Pharmaceutical Applications: used to analyze drug substances, excipients, formulations, and detect contaminants.
● Forensic Science: forensic investigations like analyzing documents for forgeries or identifying trace evidence.
