Modeling and experimental verification of bonding parameters by example of lens-alignment

Owing to their flexibility and the lower cost, in particular applications of alignment bonding as assembly and bonding technology of single lenses are widely used in optical industry. Due to these advantages, alignment bonding has been further developed for the integration of lenses and lens groups. Due to this fact, auxiliary lens mounts are no longer needed, because optical elements are bonded directly into bodies/main housings. To avoid any optical performance degradation for this application in optical systems and advanced adhesive technology, the main conditions for the success is based on an optimum bondline, defined as one that produces zero (radial) stress. In order to meet this demand a detailed knowledge of materials, joint partners / geometry and environmental impact is required for developing a mathematical model at the optic / adhesive / optic mount interface as well as the technical implementation of a new Precision Alignment of Lenses. To achieve an optimal mathematical model and zero (radial) stress bond of lenses in cells, the experimental verification has taken place with several test samples, descriptive statistics as well as interferometric measurement.
