This invention is an adhesive that is applied to the back of optical substrate mirrors such as the ones used in aerospace applications. The adhesive when applied, it provides acoustic dampening and uniform dissipation of heat, thus protecting the optical component from stress and heating. This is particularly innovative for aerospace applications where optical components require robustness against severe temperature gradients and mechanical vibrations. The adhesive’s unique composition allows for a significant enhancement in the thermal management of the mirrors and increased resiliency, which is critical for maintaining optical precision during demanding operational conditions. Background: Many optical substrates mirrors are brittle and sensitive to temperature variations that limit their applications. For example, borosilicate optics are relatively low cost and can be cast into lightweight shapes and are easy to figure to high optical precision. The invention leverages an ultra-low-modulus, high thermal conductivity adhesive applied to the backside of a light weighted optical substrate. This method improves upon the existing substrates' designs by not only increasing the acoustic damping but also by increasing the uniformity of heat dissipation. The resulting enhancement in the dynamic survival of the optic under stress conditions allows for broader application possibilities and extends the frontiers of optical substrate utilization.
