| Abstract | Most optical shops are now equipped with 5-axes grinding and polishing machines for manufacturing freeform optics. It can be advantageous to define off-axis parabolic (OAP) and ellipsoidal (OAE) mirrors as freeforms to ease their design, specification and fabrication as stand-alone wedge-less mirrors. This paper describes an algorithm generating the surface sag and sphere departure point clouds from the conjugation distances and fold angle of the mirror. |
