摘要

The device has a reflection unit (20) arranged for multiple reflection without preferred direction in such a manner a part of radiation emitted by a radiation source(14) strikes the reflection unit, and a part of radiation reflected by the reflection unit strikes a detector (16). A substance (10) which can be detected is partially arranged between the radiation source and the reflection unit in the medium.
