PHOTOSENSITIVE ELEMENT ASSEMBLY

摘要

A sensor assembly (100) comprises a housing (102) having a major face (103) and a side edge (116). The side edge is formed of a material that is capable of conducting light. A photosensitive element (120) is positioned within the housing and facing the major face of the housing. A reflector (122) is positioned within the housing. The reflector is shaped to direct light entering through the side edge onto the photosensitive element (120).
