Dymax UV Curable Optical Adhesives for Optical Bonding and Lens Assembly
About Dymax UV Curable Optical Adhesives for Optical Bonding and Lens Assembly
Dymax OP Series UV curable optical adhesives are optically clear, single-component adhesives designed for high-performance optical bonding, lens assembly, and precision photonics manufacturing. Curing in seconds with UV or visible light, these low-shrink, low-stress adhesives provide accurate component positioning, excellent optical clarity, and high bond strengths of up to 3,000 psi (21 MPa).
They bond glass, quartz, ceramics, metals, and engineering plastics, filling gaps up to 6 mm, making them ideal for lens bonding, VCSEL packaging, fibre optic assembly, optical sensor manufacture, lens fixturing, laminating, and other demanding optical assembly applications.

Dymax OP Series UV Curable Optical Adhesives for Precision Optical Bonding are used wherever optical performance and assembly accuracy are critical. They combine rapid UV curing with exceptional optical clarity and minimal cure shrinkage, allowing manufacturers to bond delicate optical components without introducing stress that could affect alignment or performance.
