Abstract:
1. A hermetic barcode sensor package comprising an optical emitter circuit having an emitter die for emitting a light beam and a diffraction optical element directly disposed on said emitter die for focusing said light beam; a optical detector circuit having a photodetector die for detecting reflective light and another diffraction optical element directly disposed on said photodetector die for guiding said reflective light to said detector; a housing having a reading surface and at least one aperture located between said reading surface and both said emitter and photodetector dies; wherein said optical emitter circuit and said optical detector circuit comprise at least one integrated optical circuit disposed in said housing; a ceramic substrate having electrodes disposed thereon; said optical emitter circuit and optical detector circuit being disposed on the upperside of said ceramic substrate in electrical contact with said electrodes; and pins in electrical contact with said electrodes.
