  • Coatings for optical drop detectors
    Patent number: 11833815
    Abstract: An example of an apparatus is provided. The apparatus includes a printhead to dispense drops of print fluid on a media. The drops are to travel along a drop path through air from the printhead. In addition, the apparatus includes a light source to emit light across the drop path. The apparatus also includes a detector to detect an intensity of the light received from the light source. The drop path is to intersect an optical path from the light source to the detector. Furthermore, the apparatus includes a coating disposed on the optical path between the drop path and the detector. The coating is to absorb a threshold amount of the light.
