Abstract
An objective lens is used for DNA sequencing. An example system includes a flow cell, the objective lens, and a camera. Light from the flow cell is imaged by the camera through the objective lens. The objective lens can provide a long working distance; a flat field curvature; a high numerical aperture; and/or a wide field of view.
