Non-contact temperature measurement sensor

Abstract:

The present disclosure is directed to a sensor package having a thermopile sensor and a reference (or dark channel) thermopile sensor disposed therein for temperature measurements. In one or more implementations, the sensor package includes a substrate, a thermopile sensor disposed over the substrate, a reference thermopile sensor disposed over the substrate, a reference temperature sensor disposed over the substrate surface, a lid assembly disposed over the thermopile sensor and the reference thermopile sensor, and a thermo-optical shield. The thermo-optical shield defines an aperture over the thermopile sensor such that at least a portion of the thermo-optical shield is positioned over the reference thermopile sensor to provide optical and thermal shielding for portions of the sensor package.
