1. Device for a light-spectroscopic analysis, comprising:
a sample holder defining a sample receiving surface on a first side extending horizontally, and an inclined surface on a second side, opposite the first side, the inclined surface extending along a plane at a non-zero angle relative to the sample receiving surface;
a mirror having an entry face on a first side, adjacent the sample receiving surface, and a reflective surface disposed on a second side opposite the first side of the mirror;
wherein the sample receiving surface of the sample holder and the entry face of the mirror are supported in a spaced apart relationship to both contact a drop of a first liquid sample, and retain the drop of the first liquid sample therebetween; and
a measuring head disposed adjacent the inclined surface and configured for emitting excitation light toward the first liquid sample along an optical axis (A), and configured for receiving signal light, the excitation light passing through the first liquid sample and is reflected off of the reflective surface to pass back through the first liquid sample, and wherein the inclined surface modifies an optical pathway of both the excitation light and the signal light.
