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.

Optical device, particularly a polarimeter, for detecting inhomogeneities in a sample

An ATR sensor has a housing and sensor components in the housing including an electromagnetic radiation source for emitting a predefined wavelength range, a reflection body permeable for radiation and contactable with a fluid to be evaluated, and a detector for the reflected radiation as well as other members for conducting the measurement and for operation. The sensor is particularly suited for measuring a COcontent of a fluid. Before sealing the housing in a gas-tight manner, in particular for avoiding a measurement value drift and for keeping the radiation paths free of CO, a COgetter material is introduced into the housing and/or into a receiving space of an additional housing that communicates with the interior space of the housing before sealing the interior space and/or the receiving space.
