Abstract
Devices, systems, and associated methods for detecting drops dispensed by a dropper are provided. For example, a drop detection device may include a light source and a light detector configured to be coupled to a drop dispenser such that the light source and light detector are disposed proximal of a distal dispensing tip of the drop dispenser. The light detector may be configured to receive a reflected portion of a beam of light from the light source, which is reflected by a drop dispensed through the dispensing tip of the drop dispenser. In some embodiments, a processing circuit is configured to analyze a signal provided by the light detector to detect the dispensed drop.
