Abstract
A photo-optic transducer assembly comprising a frame constructed to surround the peripheral edges of a ceramic hybrid circuit card such that a radiation source and a radiation responsive element coupled to said hybrid circuit card are appropriately aligned with a photo-optic light pipe assembly, also supported by said frame, the light pipe element leading to a location where sensing is to occur. The hybrid circuit card contains active and passive components (including one or more integrated circuit chips) on it for processing signals indicative of conditions being irradiated by a source of radiant energy.
