Abstract
The invention is directed to an immersion oil for microscopy. The immersion oil includes an ester or ether with tricyclodecane structure as a main constituent and one or more high-boiling liquids as minor constituents. The immersion oil is free of halogens and exhibits a high UV-transmissibility and is characterized by low intrinsic fluorescence because the components utilized can be vacuum distilled.
