[ 20. A light detection and ranging (LIDAR) device, comprising:
a housing;
a lens mounted to the housing, wherein the lens comprises a first surface that is disposed outside the housing and a second surface that is disposed inside the housing;
a plurality of light sources disposed within the housing, wherein the plurality of light sources are configured to emit a plurality of light beams in a plurality of different directions in a transmit path; and
a plurality of detectors disposed within the housing, wherein the plurality of detectors are configured to receive light through a receive path, wherein the transmit path at least partially overlaps the receive path within the housing, and
wherein the lens is configured to collect light comprising light reflected by one or more objects in an environment of the LIDAR device, and focus the collected light onto the detectors via the receive path.]
