Depth of focus is a lens optics concept that measures the tolerance of placement of the image-capturing plane (the plane of an image sensor or a film...

See also the closely related depth of focus. For cameras that can only focus on one object distance at a time, depth of field is the distance between...

In seismology, the depth of focus or focal depth is the depth at which an earthquake occurs. Earthquakes occurring at a depth of less than 70 km (43 mi)...

regions of an image which are outside the depth of field. The opposite of bokeh—an image in which multiple distances are visible and all are in focus—is deep...

is the depth of focus. For a depth of focus of 100 nm, a small local deviation from flatness of 2.5 mrad (0.14°) can lead to a pattern shift of 1 nm. Simulations...

contribute to depth perception in natural retinal images, because the depth of focus of the human eye is limited. In addition, there are several depth estimation...

Shallow focus is a photographic and cinematographic technique incorporating a small depth of field. In shallow focus, one plane of the scene is in focus while...

cameras with focus-free lenses also have a relatively small aperture, which increases the depth of field. Fixed-focus cameras with extended depth of field (EDOF)...

Deep focus is a photographic and cinematographic technique using a large depth of field. Depth of field is the front-to-back range of focus in an image...

Conventional (not Aspherical) IOLs give better depth of focus and better near vision. The reason for improved depth of focus in conventional lenses is linked to...
