- **Caution**: 

### Q: What materials are used in detection head/aperture construction?
**A**: Our detection heads/apertures are constructed from durable materials including stainless steel for corrosion resistance, anodized aluminum for lightweight strength, optical glass for clear sensing, and engineering plastics for cost-effective applications.

### Q: How does the aperture plate affect detection accuracy?
**A**: The aperture plate precisely defines the detection field opening, controlling the measurement area and minimizing environmental interference. Proper aperture sizing ensures accurate sensor readings and consistent performance in industrial environments.

### Q: What maintenance do protective windows require?
**A**: Optical glass protective windows require regular cleaning with appropriate solvents to maintain clarity. For harsh environments, we recommend periodic inspection for scratches or coating degradation that could affect sensor performance.
