The present invention relates to an optical moisture sensor of the internal reflection type which may be attached to a first surface of a transparent pane for detecting moisture on a second, opposing surface of the pane. The moisture (100) comprises at least one radiation emitter (102) for generating radiation be directed towards said second surface (106) of the pane (104), at least one radiation detector (114) for detecting radiation reflected by the second surface (106) of the pane (104), and a beam shaping unit (116) for shaping the radiation emitted by said emitter (102), wherein the beam shaping unit (116) comprises at least one collimating lens (118) for forming a first radiation beam (120) from a first portion of the emitted radiation, and at least one parabolic mirror (122) for forming at least one second radiation beam (124) from a second part of the emitted radiation.
