ABSTRACT:
A baffle for enlarging the field of view of and enhancing collection of radiation for a sensor apparatus having a transducer for receiving radiation within its field of view. The baffle includes a base securable proximate the transducer, and at least one blade element extending from the base outwardly from the transducer. The base element includes a proximal edge transecting the transducer to establish at least two apertures for the transducer for enlarging its field of view. The blade element is reflective for the radiation to enhance collection of the radiation from a periphery of the enlarged field of view.
