    Abstract: Disclosed herein is an apparatus comprising: a probe carrier comprising: a substrate comprising with holes through a thickness of the substrate and a transparent window across an opening of each of the holes, wherein the transparent window closes the opening, wherein one or more locations on the transparent window are configured to have probes attached thereto, wherein interaction between the probes and an analyte generates a signal; an optical system comprising a plurality of collimators; a sensor configured to detect the signal; wherein the collimators can essentially prevent light from passing if a deviation of a propagation direction of the light from an optical axis of the collimators is greater than a threshold. Because the probe carrier is separate and independent from the microarray, the probe carrier may be assembled with a pre-existing microarray prior to its use, and be detached from the microarray and disposed after its use.
