Paper Abstract

Anamorphic lenses entered the world of photography and cinematography quite a century ago. Since then, the propose of anamorphic lenses changed from increasing the field of view without increasing the image format on film material, to the creation of the most exciting images ever seen. Specific for anamorphic lenses is the different focal length in two perpendicular planes inside the lens system. This implies the use of asymmetric and rotational symmetric optical elements together in the same lens system. The design process becomes more difficult and time consuming than that for designing rotational symmetric lenses because in order to cover all aspects of lens performance within the optimization process, more rays have to be traced. Therefor it is mandatory for the lens designer to know what design means and techniques are to be used for accelerating the design process. This paper describes all development directions of anamorphic prime and zoom lenses since their invention. Different types of anamorphic solutions are evaluated, showing advantages and disadvantages and optimal structures and power distributions inside the lens system. This gives the designer the best options for designing this type of lenses.
