Abstract
An optoelectronic module includes a beam transmitter, which emits at least one beam of light along a beam axis, and a receiver, which senses the light received by the module along a collection axis of the receiver, which is parallel to the beam axis within the module. Beam-combining optics direct the beam and the received light so that the beam axis is aligned with the collection axis outside the module. The beam-combining optics include multiple faces, including at least a first face configured for internal reflection and a second face comprising a beamsplitter, which is intercepted by both the beam axis and the collection axis.
