Abstract
An optical system includes a first light folding element (e.g., a prism), a second light folding element (e.g., another prism or a mirror), and a lens system located between the first light folding element and the second light folding element. In some cases, the lens system includes a lens stack having either four or five lens elements with refractive power. The first light folding element redirects light from an object field from a first axis to the lens system on a second axis. The plurality of refractive lens elements in the lens stack refract the light to the second light folding element. The second light folding element redirects the light from the second axis onto a third axis to form an image of the object field at an image plane. The optical system has a 35 mm equivalent focal length within a range of 85 to 160 mm.
