Abstract
The inventive sensor device includes 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 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. In addition, the encapsulant may include an integral diffuser. Further, the sensing element may have an active sensing area of less than 1 mm2, and may be positioned closer to the surface of the integral lens than a distance corresponding to a focal length of the integral lens.
