Abstract: The present disclosure provides solid-state optical test targets useful for evaluating the performance of an optical imaging system. The solid-state optical test targets comprise at least a first substrate made from a flat transparent material. In some embodiments, the solid-state optical test targets further comprise an opaque coating that forms a micropattern. The first substrate is positioned in direct contact with the micropattern. The optical test targets described herein lack a flow cell and lack a liquid, and are therefore solid-state apparatus. Since the solid-state optical test targets lack a flow cell and liquid, the thickness of the first substrate is adjusted to simulate the presence of a hypothetic flow cell which could be located for example below the first substrate. The adjusted thickness of the first substrate can simulate the collective effects of the first substrate and the hypothetical flow cell containing a fluid/liquid.
