Because of an infinite thickness at r = 0 and vertical tangents at the substrate edge, this thickness distribution is also a tulip-like form (Fig. 2.2).

• Conclusion for VTD solution Type 3: ^ Variable curvature mirrors are obtained by uniform loading and reaction at the center provided a tulip-like thickness t = T2010 such as

with to a

where 1/R = 2A20 is the curvature of the deformation, and the product qR positive.
