- **Caution**: 

### Q: What is the primary function of a collimating lens in optical systems?
**A**: A collimating lens converts divergent or converging light from a source like a laser diode into a parallel beam, essential for applications requiring precise light direction in electronics and optical manufacturing.

### Q: What materials are commonly used for collimating lenses and why?
**A**: Optical glass (e.g., N-BK7, Fused Silica) is used for high precision and durability, while plastics (e.g., PMMA, Polycarbonate) offer cost-effective solutions for less demanding applications in electronics.

### Q: How does anti-reflection coating benefit a collimating lens?
**A**: Anti-reflection coating reduces light loss and glare by minimizing reflections at the lens surfaces, improving beam quality and efficiency in optical systems for computer and electronic products.
