Refractive index matching (RIM) of liquid and semi-solid

2020年4月11日  To increase the viscosity of the NaI solution, sucrose is added and the NaI concentration is lowered appropriately to keep the refractive index constant. This only works in a limited range, because the solution is not stable at sucrose concentrations above ca. 43%w/w. Table 1 summarises the relevant material parameters for the involved liquids.
