CATOPTRICS

Introduction to Catoptrics and Historical Context Catoptrics constitutes the foundational branch of optics specifically dedicated to the study of the reflection of light. This discipline investigates how light rays interact with and are redirected by surfaces, particularly focusing on the principles governing mirrors and other reflective elements. Unlike dioptrics, which addresses refraction (the bending of […]

SPHERICAL LENS

Definition and Fundamental Geometry The concept of the spherical lens is foundational to the field of optics, defining a category of lenses characterized by surfaces that are sections derived from the curvature of a sphere. By definition, a spherical lens is one where at least one, and typically both, of its refractive surfaces are portions […]
