Abstract
An integrated fluid ejection and spectroscopic sensing system may include a fluid ejector to eject a droplet of fluid through an ejection orifice towards a deposition site, a sensor array, a dispersive element to project light onto the sensor array. The dispersive element, the sensor and the fluid ejector are joined as part of an integrated unit.
Claims13
An integrated fluid ejection and spectroscopic sensing system comprising:
- a fluid ejector to eject a droplet of fluid through an ejection orifice towards a deposition site;
- a sensor array;
- and
- a dispersive element to project dispersed light onto the sensor array, wherein the dispersive element, the sensor array and the fluid ejector are joined as part of an integrated unit,
- wherein the dispersive element has a first focus directing different colors of light to a single spot on the sensor array and a second focus directing different colors of light to different spots along the sensor array.
