- **Caution**: 

### Q: What are the main applications of beam splitters in computer and optical product manufacturing?
**A**: Beam splitters are essential in optical data storage devices, laser printers, barcode scanners, optical sensors, and imaging systems where precise light division is required for signal processing or measurement.

### Q: How do dielectric coatings affect beam splitter performance?
**A**: Dielectric coatings determine the split ratio, wavelength specificity, and durability. They provide precise control over reflection/transmission percentages and minimize absorption losses compared to metallic coatings.

### Q: What specifications should I consider when selecting a beam splitter for electronic manufacturing?
**A**: Key specs include split ratio (50/50, 70/30, etc.), wavelength range, surface flatness, coating durability, substrate material (usually optical glass), and environmental stability for manufacturing conditions.
