1. An optical reader system comprising:
- a source light assembly configured to illuminate encoded substrates with a code-reading beam and a fluorescence-excitation beam, the code-reading beam and the fluorescence-excitation beam forming respective beam spots on the substrates, the beam spots having different shapes, the substrates having optically readable codes; and
a reader configured to receive output signals when the code-reading beam is incident upon the substrates and fluorescent signals when the substrates are illuminated by the fluorescence-excitation beam, the output signals from the code-reading beam being indicative of the codes.

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.
