Abstract

An anamorphic objective having a relatively small anamorphic factor but with relatively pronounced residual anamorphic artifacts is formed by reducing the anamorphic factor with anamorphic lens elements located on the image side of the aperture stop. The lens section on the object side of the aperture stop must therefore have a relatively large anamorphic factor, and this creates the desired residual anamorphic artifacts. The disclosed anamorphic objective is suited either to an integrated optical design or to a modular approach in which the anamorphic factor reduction optics are connected as a removable attachment to an independently well-corrected anamorphic optical system. The anamorphic objective has a relatively small anamorphic squeeze ratio while simultaneously producing relatively large residual anamorphic characteristics.
