Optical arrangement for wide angle imaging lens with front entrance pupil
Abstract:
A method and apparatus for capturing an image of at least one object appearing in a wide-angle field of view (FOV). A housing has an image sensor and a lens assembly fixedly mounted relative thereto. The lens assembly includes first and second lens groups, and a glass lens. The lens assembly and the image sensor are aligned such that light received within the FOV passes through a front aperture and the base lens assembly and impinges onto the image sensor. The light received from the FOV forms an original image prior to entering the front aperture and the lens assembly. Light from the FOV impinging onto the sensor forms an impinging image.
