Acronym Finder (AF) is a free, online, searchable dictionary and database of abbreviations (acronyms, initialisms, and others) and their meanings. The entries are classified into categories such as Information Technology, Military/Government, Science, Slang/Pop Culture etc. It also contains a database of the United States and Canadian postal codes.
An optical system that produces no net convergence or divergence of the beam, i.e. has an infinite effective focal length. [7] This type of system can be created with a pair of optical elements where the distance between the elements is equal to the sum of each element's focal length ( d = f 1 + f 2 {\displaystyle d=f_{1}+f_{2}} ).
Optoelectronic devices are electrical-to-optical or optical-to-electrical transducers, or instruments that use such devices in their operation. [ 1 ] Electro-optics is often erroneously used as a synonym, but is a wider branch of physics that concerns all interactions between light and electric fields , whether or not they form part of an ...

Optica is an optical design program used for the design and analysis of both imaging and illumination systems. [1] It works by ray tracing the propagation of rays through an optical system. It performs polarization ray-tracing, non-sequential ray-tracing, energy calculations, and optimization of optical systems in three-dimensional space.
