Abstract
A variable focal length lens device includes: a variable focal length optical system configured to change a focal length; a beam splitter configured to cause passing light, which is reflected off an object and passes through the variable focal length optical system, to branch into branched beams; an image-forming lens configured to condense the branched beams respectively; an image sensor configured to capture an image of the object by receiving the branched beam condensed by the image-forming lens; and an image sensor configured to capture an image of the object by receiving the branched beam condensed by the image-forming lens. An imaging distance on a first optical axis from the image sensor to the image-forming lens and an imaging distance on a second optical axis from the image sensor to the image-forming lens are different from each other.
