Optical N-SF11 Rhomboid Prism
The N-SF11 rhomboid prism is a parallelogram-shaped optical component made from N-SF11(H-ZF13) flint glass, known for its high refractive index and strong dispersion properties. These characteristics make it ideal for applications requiring compact optical path design or precise chromatic dispersion control.

| How to choose the material for a rhomboid prism? | |||
| Material | Refractive Index | Applicable Scene | Advantages and Disadvantages |
| BK7 | 1.517 | Visible light laser systems, precision instruments | ✅ Low absorption and high uniformity |
| ❌ High brittleness | |||
| Fused Silica | 1.46 | UV laser, high temperature environment | ✅ Heat resistance and low thermal expansion |
| ❌ High cost | |||
| SF11 | 1.78 | High refractive index requirement (reducing prism size) | ✅ Compact design |
| ❌ Large dispersion | |||
| PMMA | 1.49 | Low cost light guiding and educational demonstrations | ✅ Lightweight and easy to process |
| ❌ Poor heat resistance | |||
