1. A microscopy system, comprising:
a plurality of microfluidic ejectors;
a mirror disposed in a droplet path of the plurality of microfluidic ejectors,
wherein the droplet path passes through an opening in the mirror; and
an optical system focused on the plurality of microfluidic ejectors reflected by the mirror,
wherein the optical system comprises a camera, and
wherein the mirror is positioned directly under the microfluidic ejectors and is disposed at an angle other than orthogonal to the droplet path to direct light from the microfluidic ejectors toward the camera.
