Cylindrical Lens Creator
FRED does not currently include a built-in cylindrical lens creator. Cylindrical lenses must be entered either manually surface by surface or by adding a catalog cylindrical lens and adjusting it accordingly. This knowledge base article includes a script that generates a cylindrical lens based on user specifications entered into a Basic dialog, shown below. Using this utility cylindrical lenses can be created in much the same way as axially symmetric lenses are generated. The Cylindrical Lens Creator can be used for both circular/elliptical and square/rectangular aperture lenses and the axis of power (x or y) can be specified.
