Dayoptics has capability in manufacturing various optical components with variety of optical materials. Selecting a optical material is important since each material has different optical characteristics, such as transmission versus wavelength, index of refraction, thermal, mechanical and chemical characteristics.
The index of refraction and Abbe Number of a glass are typically used by designers as degrees of freedom when designing systems.Dayoptics has a program that combines the foundation data of a wide variety of optical materials.It is easy for us to find the right materials for your application.
Many glass manufacturers offer the same material characteristics under different trade names .Based on availability,we reserve the right to substitute ab equivalent glass in our production runs.
Herewith, the most common materials Dayoptics used:
| Material | Refractive Index(nd) | Abbe Number(Vd) | Density(g/cm3) | Transmission Range(um) | Thermal Expansion Coefficient(10-6/k) |
| BK7 | 1.517 | 64.2 | 2.52 | 0.33-2.1 | 7.5 |
| SF5 | 1.673 | 32.17 | 4.08 | 0.33-2.5 | 8.2 |
| SF11 | 1.785 | 25.76 | 4.87 | 0.37-2.5 | 6.8 |
| Fused Silica | 1.458 | 67.82 | 2.2 | 0.185-2.5 | 0.54 |
| Prexy | 1.474 | 65.38 | 2.23 | 0.23-2.7 | 3.25 |
| CaF2 | 1.434 | 94.99 | 3.18 | 0.17-7.8 | 18.85 |
| Sapphire | 1.768 | 72.24 | 3.99 | 0.18-4.5 | 5.8 |
For the Schott material in this catalogue,we use Chinese equivalent material instead
