Abstract
A self-contained optical sensor (5) with a device platform (7) and an encapsulating light transmissive housing (9) formed therein is disclosed in conjunction with several sensor configurations including fluorescence-based, surface plasmon resonance based and light transmissive (bio) chemical sensor applications. The sensor (10) has at least one light source (20), a photodetector (25), a power source (18) and a display (50) which are embedded in an encapsulating housing (14). In other embodiments, a signal processing unit (35), converter circuit (30) and wireless Communications means (40, 45) are also included in the housing (14).
