Glass population study and discrimination of glass samples using Glass Refractive Index Measurement III and scanning electron microscopy/energy dispersive X-ray spectroscopy
… analysis was performed using the Glass Refractive Index Measurement system (GRIM3®) for the measurement of refractive index and the Scanning Electron Microscope and Energy Dispersive Spectroscopy (SEM/EDS) for elemental composition of each sample. Refractive index varies with glass …

Uncertainty Considerations with the GRIM
Refractive index has been chosen as a comparison technique in glass analysis for many years. Hidden in this comparison is a quantitative measurement that requires the assessment of uncertainty. In this experiment, refractive index was performed on 63 samples from 41 sources of glass. Pairwise …

Investigation of metal nanomaterials as a sensing element in LSPR-based optical fibre sensor development
… environment. A small change for example in the refractive index or in the solution concentration can result in a variation in the LSPR spectrum. Based on this underpinning sensing mechanism, a portable system using an optical fibre coated with gold nanoparticles (AuNPs) as a sensing probe has …

Label-free Optical Approaches for the Non-invasive Assessment of Embryo Quality
… microscopy to detect spatio-temporal changes in refractive index that were associated with increased intracellular lipid abundance, in the absence of exogenous tags. This underscores the potential for refractive index measurement as a label-free indicator of embryo quality, a feature compatible …
