An apparatus includes an optical device that includes a substrate, a first layer of material over the substrate, and a second layer of material comprising an optical coating over the first layer of material. The first layer of material creates a first stress within the optical device that counteracts a second stress within the optical device created by the second layer of material. The optical device may also include a third layer of material positioned between the substrate and the first layer of material. In some cases, the second layer of material creates a compressive stress within the optical device, and the first layer of material creates a tensile stress within the optical device that counteracts the compressive stress within the optical device.

A space-stable thin film composite coating is provided that exhibits high IR emittance properties similar to OSR mirrors, and which is thin enough to be applied to a flexible substrate. The composite coating can include hundreds of alternating layers of aluminum oxide and silicon dioxide vacuum deposited to individual layer thickness of about 150 Angstroms and 50 Angstroms, respectively. The composite coating can be attached to substrates having complex geometries, for example, at various points during integration and production of hardware. The thin film can increase thermal design efficiency, reduce radiator mass and costs, and reduce production time-frames by eliminating the complexity of OSR mirror bonding.
