Abstract
The present invention provides an optical imaging lens system with double optical paths, comprising: the first optical subsystem; the second optical subsystem having a back focal length equal to that of the first optical subsystem; an optical path selector selectively having a light reflection state or a light passing state; the first reflector set disposed at an image side of the first optical subsystem for directing light from the first optical subsystem to the optical path selector; and the second reflector set disposed at an image side of the second optical subsystem for directing light from the second optical subsystem to the optical path selector. In the present invention, the optical path selector can be controlled to have the light reflection state or the light passing state selectively, so that an image coming from the first optical subsystem or from the second optical subsystem is captured.
