光線覓跡是光學設計程式的重點，雖然像差理論提供許多光學系統行為之理解，但正確的數據可以讓透鏡設計者對於其設計是否可以如預期的情況提供進一步之確定。(Light ray tracing is the focus of the optical design program, although many of the optical aberration theory provides the understanding of system behavior, but the correct data to allow the lens designer for its design, as expected, the situation can further the OK.)
