01 · Application
Application Overview
ADAS camera modules are used for lane keeping, surround view, traffic sign recognition, automated parking, and pedestrian detection. As vehicle intelligence increases, camera module production is moving from precision small-batch assembly to high-consistency volume manufacturing.
Lens focus-lock bonding is a key step. The lens-to-barrel position directly affects image quality. Cure shrinkage, dose variation, or focus drift during UV curing can lead to imaging deviation, rework, or quality risk.
02 · Challenge
Customer Challenge
After active focus adjustment, the lens position must be locked quickly and consistently. Slow cure affects takt time, while excessive shrinkage may shift focus.
Automotive environments are harsh. Camera modules must withstand temperature changes, shock, vibration, and long-term outdoor exposure.
Automotive Tier-1 quality systems require UV dose, equipment status, and process windows to be controlled and documented for customer audits and PPAP-style submissions.
03 · Solution
UV Curing Solution
OmniCure S2000 Elite is well suited for lens-to-barrel focus-lock bonding in ADAS camera modules. It delivers stable UV output to cure the adhesive quickly after focus adjustment and lock the lens position.
Closed-Loop Feedback helps reduce cure variation caused by output drift, improving focus consistency in volume production. When paired with the R2000 Radiometer, the system can support calibration and output verification across multiple stations.
This approach is especially useful for ADAS camera production lines that require stable focus, repeatable optical bonding, and documented process control.

Engineer's Note
The key metric is not simply cure speed, but whether focus remains stable after cure. Focus drift, thermal cycling image quality, and batch consistency should be validated under real equipment, adhesive, and takt-time conditions.
