Abstract (en)

[origin: DE19815932A1] A method for miniaturizing a polarimeter with a very long optical path length for analyzing low concentrated components in particular in a fluid measuring product on an optical basis, whereby the optical measuring beam is guided several times through the measuring product. The measuring beam is deflected by means of total reflection in prisms which are arranged on the outer sides of the measuring chamber or by reflection onto mirrors arranged inside the measuring chamber. A specific optical structure ensures that no modification occurs in the polarization state of the light, i.e. the angle of rotation and ellipticity thereof.
