Abstract:
Disclosed is an assay result reading apparatus for use with an assay in which a detectable substance tends to accumulate within a detection zone of the assay, the reading apparatus comprising: a housing or baffle, having a window therein; a light source which emits light through the window so as to illuminate the detection zone of the assay; and a light detector to detect the amount of light reflected and/or transmitted by the detection zone, which amount is at least partly dependent on the amount of detectable substance accumulated in the detection zone; wherein the shape of the window is adapted to render the reading apparatus less sensitive, preferably insensitive, to minor mis-positioning of the detection zone relative to one or more of the window, the light source and the light detector.
