Immersion Match
Definition
Defined optical criterion indicating close correspondence between specimen and surrounding liquid indices. Temperature and wavelength can affect refractive behaviour. A match is not automatically an exact unique composition or source identity.
- Context
- Optical comparison
For example, a fragment that appears closely matched to an immersion liquid under one condition may require temperature and wavelength control for a reproducible comparison.
Report the criterion and resolution actually achieved.
