Claim:
1. An opto-electronic sensor module comprising: a substrate; a light emitter mounted on a first surface of the substrate, the light emitter operable to emit light at a first wavelength; a light detector mounted on the first surface of the substrate, the light detector operable to detect light at the first wavelength; an optics member disposed substantially parallel to the substrate, wherein the optics member comprises first and second transparent portions that are transparent to light at the first wavelength, the optics member further comprising a blocking portion that substantially attenuates or blocks incident light at the first wavelength, and wherein the first transparent portion is disposed above the light emitter and the second transparent portion is disposed above the light detector; and a separation member that is disposed between the substrate and the optics member, surrounds the light emitter and the light detector, includes a wall portion that extends from the substrate to the optics member and that separates the light emitter and the light detector from one another, and is composed of a thermosetting polymer material, a UV-curing polymer material or a visible light-curing polymer material, wherein the separation member further includes one or more inorganic fillers that make the separation member substantially non-transparent to light detectable by the light detector.
