angular magnification -> magnification

The ratio of the size of the image of an object to that of the object. The ratio of the linear size of the image to that of the object is lateral magnification. Angular magnification is the ratio of...

absolute magnification

The value of the distance of distinct vision, minimum focusing distance or near point, divided by the focal length of the lens. Magnification is produced when the optic is placed at its focal...

Abbe prism

A form of roof prism used to invert an image. The prism has faces cut normal to the optical axis; therefore, the prism may be placed within the optical path of a system and invert the image without...

anamorphic

A term used to denote a difference in magnification along mutually perpendicular meridians. Anamorphic systems are basically image-distorting systems, such as those used in motion pictures, that...

anamorphic distortion

A type of distortion in which the magnification varies in different orientations, the directions of maximum and minimum magnification being orthogonal.

anamorphic system

An optical system with different focal lengths or magnification levels in perpendicular planes to the optical axis.

astronomical telescope

An astronomical telescope is a type of optical instrument designed to gather and magnify light from distant celestial objects for observation and analysis. It typically consists of two main optical...

auxiliary telescope

A low-power telescope placed at the eyepiece of an optical system to increase overall magnification. Most often used to evaluate image quality.
