Abstract
An optical reader system that includes a plurality of substrates. The substrates have an optically readable code disposed therein and a source light assembly that is configured to illuminate the substrates with a code-reading beam and another beam for detecting another optically readable property of the substrate. The code-reading beam and the other beam form beam spots on the substrates that have different shapes. The system also includes a reader that is configured to receive output signals from the code-reading beam and the other beam when the substrates are illuminated. The output signals from the code-reading beam are indicative of the code.
