Abstract: Recent advances in photon detection provide cutting-edge optical measurements that are accessible to undergraduate physics and chemistry labs. Furthermore, the advent of affordable auto-balanced photoreceivers increases the likelihood of shot noise limited measurements becoming a reality. However, minor obstacles must be overmore before there is implementation of relative rigorous training and research that would involve such measurements. First, the measurement theory pertaining to an appropriate experiment should be relatively transparent. Second, instrumentation issues based on fundamental principles of optics should be realized through simpler, yet similar, experiments. This work provided sufficient background to help overcome both of these hurdles. Essentially, some key foundational aspects of dual beam photometry are addressed utilizing a previously designed crossed-beam spectropolarimeter. The instrument was assembled and evaluated utilizing the optical rotatory dispersion (ORD) of sucrose.
