Abstract:
1. An optical sensor device, comprising: a light source die including one or more light emitting elements; a light detector die including one or more light detecting elements; a first opaque light barrier portion configured to block light from being transmitted directly from the light source die to the light detector die, said first opaque light barrier portion between the light source die and the light detector die; a light transmissive material covering the light source die and the light detector die; and a second opaque light barrier portion configured to reduce an amount of specular reflections, if a light transmissive cover plate were placed over the optical sensor device; said second opaque light barrier portion extending from the first opaque light barrier portion, in a direction towards the light source die, a distance greater than an entire gap between the first opaque light barrier portion and at least one of the one or more light emitting elements of the light source die; wherein the first opaque light barrier portion separates a portion of the light transmissive material covering the light source die from a portion of the light transmissive material covering the light detector die; and wherein the second opaque light barrier portion extends over a portion of an outermost surface of the portion of the light transmissive material covering the light source die.
