Material Guide
Silicon (Si)
Durable infrared material suitable for NIR to MWIR optics and rugged windows.
Material Introduction
Silicon provides strong mechanical properties and broad usage in cost-sensitive infrared optical assemblies, especially where durability and thermal stability are required.
Optical Performance
| Metric | Typical Value |
|---|---|
| Transmission Range | 1.2 - 8 um |
| Refractive Index (5 um) | ~3.42 |
| Hardness (Mohs) | ~7 |
Applications
- IR protective windows
- Industrial sensing optics
- NIR/MWIR imaging modules
Comparison Notes
Silicon often delivers stronger mechanical robustness than ZnSe. Compared with Ge, it is usually lighter and suited to shorter infrared wavelength bands.
