Abstract
A method comprises: directing, using an objective and a first reflective surface, first autofocus light toward a sensor, the first autofocus light reflected from a first surface of a substrate; preventing second autofocus light from reaching the sensor, the second autofocus light reflected from a second surface of the substrate; and directing, using the objective and a second reflective surface, emission light toward the sensor, the emission light originating from a sample at the substrate.
