Latest Patents
One of his latest patents is titled "Parabolic membrane mirror having a shape-restorative force." This invention describes an optical quality, freestanding, compliant membrane mirror that is cast with a concave parabolic shape. The mirror includes a substrate and a reflective stress coating that is in compression. This coating applies a tensile shear stress to the substrate, opposing the intrinsic stress that would otherwise decrease the concavity of the mirror. The stress coating generates a force that restores the membrane mirror to its original concave parabolic shape when deformed by external forces.
Another significant patent by Marker is the "Method of centrifugally casting a parabolic membrane mirror having a shape-restorative force." This method outlines the fabrication of an optical quality, free-standing, compliant parabolic membrane mirror using an inverted parabolic mandrel. The mandrel is created by rotating a liquid confined to a cylindrical polymer. Once the substrate has hardened, a reflective optical stress coating is applied. This coating not only offsets the stress in the substrate but also generates a force to restore the mirror to its original convex parabolic shape when deformed.
