Abstract
The inventive sensor device provides different fields of view in transverse directions. The sensor device include a support structure, a sensing element mounted on the support substrate for sensing optical radiation and generating an electrical output signal in response thereto, and an encapsulant encapsulating the sensing element on the support structure. The encapsulant includes an integral anamorphic lens. Alternatively or additionally, the encapsulant may have at least a first zone and a second zone, where the second zone exhibits at least one different characteristic from the first zone, such as a different optical, physical, thermal, or compositional characteristic.
