In this work, we present a non-contact measurement method for characterizing complex freeform optical surfaces called UltraSurf. A series of measurements using the UltraSurf have been demonstrated for traditional optical surfaces, such as flats and spheres, in addition to mild to "wild" aspheres and freeforms Each shape has its own unique challenges and benefits, including complexity of motion path and required number of motion axes. This data serves as the basis for measuring complex freeform shapes such as toroids, ogives, and pure freeforms.
