Zusammenfassung:An ultra-wide angle imaging apparatus is provided, comprising a first optics having a first optical axis, a second optics having a second optical axis, and a prism placed at an intersection of the first and second optical axis. The prism is configured to reflect light from the first optics to the second optics and the second optics is configured to transmit light from the prism to an image surface. The first optics has a negative optical power, the second optics has a positive optical power, and the prism has an entrance surface for receiving light from the first optics and a reflective inner surface for reflecting light to the second optics. The entrance surface of the prism comprises a paraxial region that is concave.
