Abstract
The two main fixing methods in the assembly process of optical components are adhesive bonding and thread fastening. For both methods, boundary loading effect is generated on optical component, which results in stress distribution in it. The quantitative prediction and control of the stress distribution in optical component is not available because the boundary load induced by adhesive or thread is difficult to control and test quantitatively. Up to now, the interrelationship and variation between the boundary load and the internal stress in optical component have not been effectively studied. Based on the above requirements, quantitative radial boundary loading and real-time measuring methods for optical component are proposed in this paper. Quantitative interrelationship between the boundary load and the stress distribution and surface form in optical component can be obtained by integrating the stress and surface measurement devices with radial boundary loading system. This innovative loading and measuring device is suitable for various sizes of optical components, and it solves the quantitative application and control problems during loading, measuring, and real-time detection of adhesive curing force.
