On April 29, 2026, a professional guide on lens-fixing adhesives for optical lens assembly optomechanical system design was released, defining two major selection directions: fast-curing and slow-curing stress-free types, providing standardized solutions for vehicle lenses, high-precision optical systems and other scenarios. The guide states that adhesives are core materials ensuring lens positioning accuracy and imaging quality. Fast-curing adhesives greatly improve mass production efficiency for camera modules, while low-stress and zero-shrinkage adhesives meet the demands of high-precision applications such as lithographic objectives and astronomical optics. Combining international benchmark products and Chenguang series, the guide recommends models like DG-5 and GD414, standardizes dispensing thickness, curing parameters and other process points, and emphasizes quality control such as surface cleaning and stress monitoring. This guide promotes the standardization of optical bonding materials, facilitating the transformation of optomechanical assembly from efficiency-first to accuracy and reliability, and accelerates the localization of high-end optical devices.
