A microtiter plate reader is disclosed which allows visual examination of the contents of the wells of a microtiter plate having an array of wells. The microtiter plate reader includes supporting means for supporting the microtiter plate with the wells opening generally upwardly and a light emitting surface is adapted to extend under a microtiter plate so held. Regions of reduced light emission on the light emitting surface are arranged in an array corresponding in relative position to a selected portion of the array of microtiter plate wells. Locator means are provided for locating the microtiter plate with respect to the array of regions of reduced light emission to allow selective alignment of the wells with the dark regions, providing a dark background to the bottom of the wells which are then illuminated indirectly. The wells can be illuminated directly when the dark regions are out of alignment with the wells.

A microtiter plate reader for optically examining the contents of the wells of a microtiter plate having an array of wells, comprising: (a) supporting means for supporting the microtiter plate with the wells opening generally upwardly; (b) a light emitting surface extending under a microtiter plate when held by the supporting means to transmit light upwardly to the plate; (c) an array of regions of reduced light emission on the light emitting surface corresponding in relative position to a selected portion of the array of microtiter plate wells when held by the supporting means, wherein the array of regions of reduced light emission is a selected number of black dots arranged as a black dot array, each black dot generally corresponding in location to a well; and (d) locator means for locating the microtiter plate in selected relation to the black dot array of regions of reduced light emission such that the array of black dots can be selectively aligned or disaligned with the wells of the plate.
