photographic optics
11Index of optics articles — Optics is the branch of physics which involves the behavior and properties of light, including its interactions with matter and the construction of instruments that use or detect it.[1] Optics usually describes the behavior of visible,… …
12Dispersion (optics) — This article is about dispersion of waves in optics. For other forms of dispersion, see Dispersion (disambiguation). In a prism, material dispersion (a wavelength dependent refractive index) causes different colors to refract at different angles …
13Filter (optics) — Coloured and Neutral Density filters Optical filters are devices which selectively transmit light of different wavelengths, usually implemented as plane glass or plastic devices in the optical path which are either dyed in the mass or have… …
14List of photographic equipment makers — This list of photographic equipment makers lists companies that manufacture (or license manufacture from other companies) equipment for photography. Camera and lens manufacturers Note that producers whose only presence in the photo industry at… …
15Objective (optics) — Several objective lenses on a microscope. In an optical instrument, the objective is the optical element that gathers light from the object being observed and focuses the light rays to produce a real image. Objectives can be single lenses or… …
16Depth of field — The area within the depth of field appears sharp, while the areas in front of and beyond the depth of field appear blurry …
17Optical aberration — v · d · e Optical aberration …
18Circle of confusion — For the closely related topic in microscopy, see Point spread function. In optics, a circle of confusion is an optical spot caused by a cone of light rays from a lens not coming to a perfect focus when imaging a point source. It is also known as… …
19Numerical aperture — The numerical aperture with respect to a point P depends on the half angle θ of the maximum cone of light that can enter or exit the lens. In optics, the numerical aperture (NA) of an optical system is a dimensionless number that characterizes… …
20Désiré van Monckhoven — Désiré Charles Emanuel van Monckhoven. Désiré Charles Emanuel van Monckhoven (1834–1882) was a Belgian chemist, physicist, and photographic researcher. He was also an inventor and author.[1] He wrote several of the earliest books on photography… …
