Claim 0:
1. A system comprising:
a light emitter configured to emit a beam having a slow axis and a fast axis so that the beam has a divergence angle difference between a first divergence angle in a horizontal direction and a second divergence angle in a vertical direction, and a cross-section of the beam has a width greater than a height;
a sensor;
a first three-element lens optically aligned with the light emitter; and
a second three-element lens optically aligned with the sensor,
wherein the first three-element lens includes a positive lens including at least one non-spherical surface based at least in part on the divergence angle difference, the positive lens having an astigmatism that reduces the width of the beam with respect to the height.
