OPTICAL ELEMENTS, SYSTEMS OR APPARATUS

Description

G02B covers optical components, assemblies, and systems designed to control, direct, or modify light propagation. This subclass encompasses lenses, mirrors, prisms, diffractive elements, filters, polarizers, beam splitters, and optical coatings, as well as integrated optical systems such as microscopes, telescopes, and viewing devices. Also included are optical design principles, aberration correction methods, and auxiliary components like mounts and alignment mechanisms. Adjacent subclasses G02C and G02D address spectacles/contact lenses and optical measuring instruments respectively, while G02F covers electro-optical devices with active control of light properties.
