A system for positive dispense verification, the system comprising: a plurality of light detectors; a plurality of light emitters, wherein light transmitted from the light emitters is directed toward the plurality of light detectors; a liquid dispense device positioned above a light curtain defined by the light directed from the plurality of light emitters toward the plurality of light detectors such that liquid dispensed from the liquid dispense device will travel through the light curtain; an amplifier communicatively coupled to the plurality of light detectors, wherein the amplifier generates a signal in response to an interrupt in a transmission of light from the plurality of light emitters to the plurality of light detectors; and a target plate onto which liquid is to be dispensed, wherein the light curtain is horizontal and parallel to the target plate, wherein the plurality of light emitters includes an array of LEDs (27A-H), distributed in a row spaced approximately equidistant from one another so that when light is generated, light beams from each LED (27A-H) overlap creating the light curtain with no gaps that would allow a droplet to pass through the curtain without registering a disrupted signal, wherein a same number of light detectors (28A-H) are positioned in a linear detector array so that each detector (28A-H) of the detector array corresponds to an LED (27A-H) of the array of LEDs (27A-H), such that the detector array has approximately the same dimensions as the LED array, wherein a space between the plurality of light emitters and the plurality of light detectors is large enough to accommodate the target plate. a plurality of light detectors; a plurality of light emitters, wherein light transmitted from the light emitters is directed toward the plurality of light detectors; a liquid dispense device positioned above a light curtain defined by the light directed from the plurality of light emitters toward the plurality of light detectors such that liquid dispensed from the liquid dispense device will travel through the light curtain; an amplifier communicatively coupled to the plurality of light detectors, wherein the amplifier generates a signal in response to an interrupt in a transmission of light from the plurality of light emitters to the plurality of light detectors; and a target plate onto which liquid is to be dispensed, wherein the light curtain is horizontal and parallel to the target plate, wherein the plurality of light emitters includes an array of LEDs (27A-H), distributed in a row spaced approximately equidistant from one another so that when light is generated, light beams from each LED (27A-H) overlap creating the light curtain with no gaps that would allow a droplet to pass through the curtain without registering a disrupted signal, wherein a same number of light detectors (28A-H) are positioned in a linear detector array so that each detector (28A-H) of the detector array corresponds to an LED (27A-H) of the array of LEDs (27A-H), such that the detector array has approximately the same dimensions as the LED array, wherein a space between the plurality of light emitters and the plurality of light detectors is large enough to accommodate the target plate.
