Lens Evaluation Kit LH112
3.3.1 Overview
The LH112 lens evaluation kit is an accessory for the XM112/XB112 evaluation kit. The lenses can be
used to increase sensor performance. The lenses increase signal strength by focusing the beam width
of the radiated EM-waves and thereby concentrating the emitted power. The lens kit is sold separately
from XM112 and XB112.
