Lens carrier and optical module for a light curtain and fabrication method
First Claim
1. An optical module for a light curtain associated with monitoring a protective field, said optical module comprising:
- a lens carrier having;
at least one lens for focusing a radiation beam associated with the light curtain;
a lens mask having at least one opening for shaping the radiation beam to have a predetermined aperture; and
wherein said lens carrier is formed by overmolding said lens mask with a transparent material; and
a module body for mounting said lens carrier and a radiation transmitter/receiver carrier that comprises at least one transmitter and/or receiver for transmitting and/or receiving said radiation and positionally associated with the lens carrier; and
wherein said module body comprises a stabilization element that is integrated into the module body for enhancing mechanical stability of the module body and wherein said lens mask and said stabilization element are fabricated from an electrically conductive material for forming an electromagnetic shielding.
