Lens fixing inside devices

Choosing the right adhesive is critical. UV-curable adhesives have become the preferred choice for modern optical assemblies, especially for cameras, smartphones, and sensors. Their ability to cure rapidly under UV light allows manufacturers to achieve precise positioning, high throughput, and consistent quality in mass production. Among these, acrylate-based UV adhesives are particularly popular due to their:

• Exceptional optical clarity : ensuring no compromise in image quality.
• Strong mechanical properties : resisting vibration, shocks, and thermal stresses.
• Excellent chemical and environmental resistance : protecting optics from moisture, dust, and other contaminants.

Lens fixing with high-performance adhesives and sealants is a critical step in modern device manufacturing. These materials ensure lenses remain precisely aligned, durable, and protected, even under demanding conditions. Whether in a smartphone camera, a security system, or industrial imaging equipment, the right adhesive solution directly translates to sharper images, longer-lasting devices, and superior user experiences.

For example, mounted cameras inside automobiles perfectly illustrate the demanding requirements an adhesive must meet. These optical modules are exposed to constant vibrations, shocks from bumps or collisions, and temperature fluctuations throughout the vehicle’s lifetime. At the same time, they must remain precisely aligned to ensure accurate imaging for applications such as driver assistance systems or 360° surround cameras. Adhesives used in these assemblies must therefore combine high mechanical strength, impact and vibration resistance, thermal stability, and long-term durability, all while maintaining optical clarity and resisting environmental factors like moisture, dust, and chemical exposure.
