Abstract
An optical device includes a support structure configured to retain an optical element using a cured adhesive composition that is disposed between a surface of the support structure and a surface of the optical element, wherein a structured optical particulate material is dispersed throughout the cured adhesive. The structured optical particulate material redirects curing radiation via a scattering mechanism to facilitate curing of portions of the adhesive compositions that cannot be directly exposed to the radiation, thereby facilitating rapid and more thorough curing than could otherwise be achieved without the structured optical particulate material.
