Abstract
Fundamental optical concepts are utilized across all fields of scientific instrumentation. In the case of beam-like systems in neutron scattering instrumentation (low-divergence trajectories taken over long distances), quantities describing a system can be scaled into dimensionless figures of merit that convey performance characteristics and geometric limits. Furthermore, this first-principles approach facilitates a straight forward means by which to tailor an optical system to a defined source-sample configuration, as well as further inform guide surface shapes and reflectivity requirements. These principles will be presented and applied incorporated to examples showing their relevance to practical applications and future instrumentation.
