Claim:
1. A sensor module for sensing a magnitude, the module being an opto-electronic module comprising a first substrate member; a third substrate member; a second substrate member arranged between said first and third substrate members and comprising at least a first and a second transparent portion through which light can pass and at least one blocking portion, wherein each of said transparent portions is surrounded laterally by said at least one blocking portion in a plane perpendicular to a stacking direction of the substrate members, and wherein said transparent portions comprise at least a first optical structure; a second spacer member comprised in said second substrate member or comprised in said third substrate member or distinct from and located between these, which comprises at least one opening; a light detecting element arranged on and electrically connected to said first substrate member; a light emission element arranged on and electrically connected to said first substrate member; a sensing element comprised in or arranged at said third substrate member, wherein said sensing element is sensitive to changes in said magnitude; and a first spacer member comprised in said first substrate member or comprised in said second substrate member or distinct from and located between these, which comprises at least a first and a second opening which are separated from each other by a portion of the first spacer member, wherein the at least one blocking portion is non-transparent to light detectable by the light detecting element, and wherein the first spacer member is, at least in part, non-transparent to light detectable by the light detecting element to reduce optical cross-talk between the light emission element and the light detecting element.
