Hamilton's Optics: Characterizing Ray Mapping and Opening a Link to Waves

Because of the simplicity of his characterization of the map from the rays at the entry of an optical system to those at its exit, Hamilton's methods spawned new insights into the limits of system performance. Remarkably, his methods are sometimes dismissed as being either esoteric or overly complicated. more>>


The Importance of Scatter in Stray Light Analysis

Scatter is a complex phenomenon and scatter data are essential to stray light analysis and surface selection. Conducting a stray light analysis early in the system design process saves time and money in design and manufacturing costs. more>>


The 200th Anniversary of Thomas Young's Wave Theory

Thomas Young presented his wave theory of light, which included the phenomenon of interference. Young presented his theory to fellows of the Royal Society in a lecture entitled "On the Theory of Light and Colours." This article describes some of Young's ideas about light, and the response they elicited from his contemporaries. more>>
