Abstract
Provided is a magnification-purpose external optical module external to a portable terminal at which a camera is installed, and a magnification imaging device including the module. An external optical module of the present invention may use an LED and a camera internal to a portable terminal such as a smart phone and thus capture a a high magnification image without a separate lighting source. Furthermore, an external optical module of the present invention does not need to use a separate lighting source because its thickness is implemented to be significantly thin and thus its focal length is designed to be significantly short, and it is possible to sufficiently illuminate a subject with a relatively distant LED in contrast to a thinned thickness.
