摘要： An example device includes an array of sensor modules. A sensor module includes a body to be positioned in alignment with a planar target, a light source coupled to the body to emit light to the planar target along a source optical path, and a plurality of light sensors coupled to the body. Each light sensor is to sense a different wavelength of light received from the planar target along a sensor optical path. The sensor optical path is different from the source optical path. The bodies of the array of sensor modules are arranged in a planar tiling pattern with respect to a longitudinal axis of the planar target.

摘要： In an implementation, a printhead includes a printhead die molded into a molding. The die has a front surface exposed outside the molding to dispense fluid drops through nozzles and an opposing back surface covered by the molding except at a channel in the molding through which fluid may pass directly to the back surface. The die also has a nozzle health sensor molded into the molding to detect defective nozzles in the printhead die.

摘要： In one example, a drop detector includes a light source for illuminating drops passing through a drop zone, multiple light detectors near the light source for detecting light scattered off drops passing through the drop zone, and multiple lenses each configured to focus light from the drop zone on one of the light detectors. In one example, each light detector is arranged in the same plane with all of the other light detectors. In one example, the lenses are configured to focus light from two different spaces in the drop zone on different detectors or groups of detectors. In one example, the lenses are configured to focus light from a single space in the drop zone on multiple detectors.

摘要： A nucleic acid detection device includes a microfluidic opening and a sensor stack. The sensor stack includes an electrochemical electrode and a photodetector. The electrochemical electrode is formed of a conductive material that is transparent to a fluorescent emission, the electrochemical electrode including a first side and an opposite second side, wherein the first side is exposed to the microfluidic opening. The photodetector is positioned relative to the second side of the electrochemical electrode to optically receive the fluorescent emission when passed through the electrochemical electrode.

摘要： In some examples, a print cartridge includes a monolithic molding, and a printhead die embedded into a molding. The printhead die has a front surface exposed outside the molding to dispense fluid drops through nozzles and an opposing back surface covered by the molding except at a channel in the molding through which fluid is to pass directly to the back surface. The printhead die also has a nozzle health sensor molded into the molding to detect defective nozzles in the printhead die.
