Abstract
An optical device, particularly a polarimeter, is provided for analyzing a liquid sample, having: a light-generating system for generating light for the surface irradiation of the sample; a detection system which is set up for the spatially resolved detection of light which originates from the transmission of the light provided for the surface irradiation through the sample; a telecentric optical system with a lens between the sample and the detection system and with an aperture diaphragm in the focal plane of the lens between the lens and the detection system.
