The present application discloses a mobile terminal with a built-in anamorphic lens, the mobile terminal is provided with a widescreen anamorphic lens which comprises a cylindrical lens group and a spherical lens group, the cylindrical lens group at least comprises a group of cylindrical negative optical power lenses and a group of cylindrical positive optical power lenses. A widescreen anamorphic lens is arranged in the mobile terminal. The optical characteristics of the cylindrical lens in the widescreen anamorphic lens are utilized to “compress” the incident light entering horizontally while keeping the incident light entering vertically unchanged, so the widescreen anamorphic lens may compress a widescreen image into a standard image area. After the compressed picture taken by the widescreen anamorphic lens is deformed and corrected by the image correction module, widescreen images and videos may be obtained, meeting the needs of users for widescreen shooting by the mobile terminal.

The present disclosure provides an optical system that includes a prism having an incident surface, an exit surface, and one or more reflecting surfaces. A first intermediate imaging position of a light flux in a first direction is located inside the prism. The first intermediate imaging position is different from a second intermediate imaging position of the light flux in a second direction orthogonal to the first direction.

A camera system including a first imaging sensor having a first imaging surface with a first diagonal length, a first lens arranged to guide a first image formation light flux toward the first imaging surface with the first image formation light flux having at the first imaging surface a width equal to or greater than the first diagonal length, a second imaging sensor having a second imaging surface with a second diagonal length, a second lens arranged to guide a second image formation light flux toward the second imaging surface with the second image formation light flux having at the second imaging surface a width equal to or greater than the second diagonal length. The first lens and the second lens are oriented in opposing directions, and the first imaging sensor, the first lens, the second imaging sensor, and the second lens are each mounted partially within an enclosure.

Single fold optical systems that include a power prism and a lens stack including two or more refractive lens elements. The single fold optical system may provide a long mechanical back focus without increasing the Z-height of the optical system. Providing power on the prism may reduce the optical total length and reduce the X-length of the optical system. The single folded optical systems may provide reduced Z-axis height and reduced X-axis length when compared to conventional double folded optical systems with similar optical characteristics. In addition, the optical systems may include an anamorphic lens that is oriented to correct for astigmatism caused by surface errors of the reflective surface of the prism.

A see-through free-form head-mounted display including a wedge-shaped prism-lens having free-form surfaces and low F-number is provided.
