Abstract
The internal propagation of radiation between a radiation source and radiation detector mounted within a sensor package is prevented by the use of an optical isolator. The optical isolator is formed by the combination of a baffle mounted between the source and detector and a groove formed in an upper surface of the sensor package between the source and detector. A bottom of the groove is positioned adjacent to an upper edge of the baffle.
