Abstract

The invention provides a light redirecting optical module for a light curtain comprising a passive optical element, especially a mirror or a prism, for changing the direction of an incident light beam, a carrier unit to which the passive optical element is fixed in a rigid manner, a support unit, wherein the carrier unit has a curved surface at a side facing away from the passive optical element and the support unit has a complementary curved surface facing the curved surface of the carrier unit, wherein the curved surfaces together form a rotary j oint, engagement means for keeping the two curved surfaces engaged to each other so as to allow for a guided rotary movement of the two surfaces relative to each other. The invention further provides a passive component of a light curtain comprising one or more passive elements for redirecting a light beam received from an emitter of the light curtain such that the light beam leaving the passive component impinges on an associated receiver of the light curtain for detecting a light beam emitted by the emitter, wherein the passive component comprises one or more of such light redirecting optical modules and a method for aligning passive optical elements in such a passive component.
