Abstract:
1. An optical sensor device, comprising: a light source including one or more light emitting elements; a light detector including one or more light detecting elements; a light transmissive material molded over and encapsulating the light source and the light detector; an opaque light barrier including a first portion and a second portion that extends from the first portion; wherein the first portion of the light barrier is between the light source and the light detector; and wherein the second portion of the light barrier extends from the first portion of the light barrier a distance greater than an entire gap between the first portion of the light barrier and at least one of the one or more light emitting elements of the light source, in a direction towards the light source, such that a portion of the second portion of the light barrier extends over at least a portion of at least one of the one or more light emitting elements of the light source; wherein the first portion of the light barrier separates a portion of the light transmissive material molded over and encapsulating the light source from a portion of the light transmissive material molded over and encapsulating the light detector; wherein the second portion of the light barrier portion covers and is located on a portion of an outermost surface of the portion of the light transmissive material molded over and encapsulating the light source; and wherein the second portion of the light barrier is configured to reduce an amount of specular reflections, if a light transmissive cover plate were placed over the optical sensor device.
