Active Alignment
What is Active Alignment?
Active Alignment is a high-precision manufacturing process where optical or electronic components are actively aligned and fixed in their optimal position during the adhesive curing process. This process enables highest precision in component positioning.
Properties of Active Alignment Adhesives
- Controlled curing speed for precise adjustment
- Minimal shrinkage to maintain positioning
- High dimensional stability across temperature range
- Excellent optical properties
- Reversible systems for readjustment possible
Applications
- Camera modules: Alignment of lenses to image sensors
- Fiber optics: Precise positioning of optical fibers
- Laser diodes: Optimal beam coupling and guidance
- Optical sensors: Exact component alignment
Process Advantages
- Maximum precision: Alignment in micrometer range
- Real-time control: Continuous monitoring of optical parameters
- Process efficiency: Adjustment and fixation in one operation
- Reproducibility: Consistent quality in series production
