An optical module for an optical unit associated with forming a light curtain for monitoring a protective or surveillance field. The optical module includes at least one radiation emitting and/or radiation receiving element for transmitting and/or receiving a radiation beam associated with forming a light curtain. The optical module includes a module body for mounting a radiation transmitter/receiver carrier that carries the at least one transmitting and/or receiving element associated with the radiation beam. The module body has at least one alignment element for aligning the optical module within a support element that forms an outer housing of the optical unit.

Optical module and optical unit for a light curtain, and fabrication method

A lens carrier and an optical module for forming a light curtain associated with monitoring a protective field. The lens carrier includes at least one lens for focusing a radiation beam forming said light curtain and a lens mask having at least one opening for shaping the radiation beam to have a predetermined aperture. The lens carrier is formed by overmolding said lens mask with a transparent material. The optical module has such a lens carrier and a module body for mounting a radiation transmitter/receiver carrier that comprises at least one transmitter and/or receiver for transmitting and/or receiving said radiation.

Lens carrier and optical module for a light curtain and fabrication method

The present invention relates to light curtains, in particular safety light curtains, for monitoring a protective field. Furthermore, the present invention relates to optical units which are part of such a light curtain. An optical unit for an alignment system of a light curtain monitoring a protective field comprises an optical processing element for generating a defined radiation pattern from the radiation emitted by an alignment radiation source, and at least one optical wave guide for guiding radiation from at least one display radiation source to a surface of the optical element which is visible to an observer.

Integrated laser alignment aid using multiple laser spots out of one single laser

The present invention relates to light curtains, in particular safety light curtains, for monitoring a protective field. Furthermore, the present invention relates to optical units which are part of such a light curtain. An optical unit for an alignment system of a light curtain monitoring a protective field comprises an optical processing element for generating a defined radiation pattern from the radiation emitted by an alignment radiation source, and at least one additional optical functional element being formed integrally with the optical processing element.
