Abstract

Various techniques for dispensing liquids are disclosed herein. In one embodiment a dispenser retention apparatus includes a frame. The frame includes a top surface configured to retain a liquid dispensing assembly. The frame also includes a bottom surface opposite the top surface. The bottom surface includes a first channel extending from a first lateral edge of the frame to a droplet passage between the top and bottom surfaces. The first channel is configured to allow a light beam introduced to the frame at the first lateral edge to intersect a droplet in the passage.
