Claim 18:
19. The method of claim 18, wherein the first material comprises a first resin that is transparent to a first wavelength and the second material comprises a second resin that is opaque to the first wavelength; and
the method further comprising:
mounting an emitter, that emits light at the first wavelength, proximate to the first portion of the first material, wherein emitted light passes through the first portion; and
mounting a detector, that detects light at the first wavelength, proximate to the second portion of the first material, wherein detected light passes through the second portion;
wherein the third portion of the second material that extends beyond the outer surface and the inner surface of the first structure is positioned between the emitter and the detector and blocks at least a portion of the light from the emitter from reaching the detector.
