Abstract
A device (100) for assisting in optical characterisation of a sample fluid. The device can comprise a substrate (102) with at least one measurement reservoir (104) adapted for filling with the fluid (106) in a filling direction. The device (100) thereby is adapted for receiving an illumination beam (108) for illuminating the fluid (106) in the at least one measurement reservoir (104). The at least one measurement reservoir is adapted for varying the rate of change of an optical path length of the illumination beam in the fluid. The measurement reservoir properties are adapted for providing information of an optical path length of the illumination beam in the fluid at a plurality of moments during the filling with the fluid. Furthermore a corresponding optical characterisation device is described. The invention also relates to a corresponding method.
