- **Caution**: 

### Q: What is the primary function of a collimating mirror in optical systems?
**A**: A collimating mirror converts divergent or convergent light beams into parallel rays, ensuring accurate light direction in spectrometers and other optical instruments for precise measurements.

### Q: Which material is best for high-temperature applications in collimating mirrors?
**A**: Fused silica with reflective coating is ideal for high-temperature environments due to its low thermal expansion and excellent thermal stability, maintaining optical performance under varying conditions.

### Q: How does the reflective coating affect collimating mirror performance?
**A**: The reflective coating determines reflectivity, wavelength range, and durability. Metallic coatings (like aluminum) offer broad spectral range, while dielectric coatings provide higher reflectivity for specific wavelengths in spectrometer applications.
