Layout of the focal plate. Left: the envelopes were iteratively squeezed together, with three key constraints: fiber tips stay on the asphere, the central axis matches the chief ray, and the pattern along one edge of the 36° petal is a straight line (see Section 2.2). Right: an axisymmetric tolerance envelope was defined by five conical sections.
