About Dymax UV Curable Optical Assembly Adhesives

Dymax OP low-stress, low-movement UV curable optical assembly adhesives cure in seconds with UV/visible light to provide strength and clarity. Optically clear, high-tensile-strength bonds of 3,000 psi and shrinkage as low as 0.1% are possible.

UV curable optical adhesives for optical assembly and lens bonding include grades for VCSEL potting, lens fixturing, lens laminating, lens positioning, and fiber-optic assembly. Dymax optically clear adhesives feature low-shrink, low-stress characteristics, are single component, and exhibit gap filling to 6mm.

Dymax OP UV Curable Optical Assembly Adhesives

OP series UV/Visible light cure optical adhesives are ideal for optical assembly applications such as lens and optical mounting and the attachment of ceramic, glass, quartz, metal, and plastic components.
