Henkel has developed a new adhesive – Loctite 3296 – a dual-cure adhesive for lens bonding in ADAS sensors. The new product provides a very high-cure depth after only a few seconds of exposure to UV-light and is designed to bond particularly well to aluminum and FR4.
When precision is key, the active-alignment assembly process is vital to deliver components of the required quality: The active alignment workflow allows for the optical components to be positioned, and then finely adjusted to ensure optimal focus before being cured in place. Compared to a threaded lens barrel that can only be adjusted in the z-direction, active-alignment allows for six-degrees of freedom in the alignment process, with an accuracy of 100 nanometers.
