MG-Optics has rich experience in custom precision Optical Components manufacture and metrology. fused silica JGS2 aspheric mirror is commonly used in telescope mirror systems.
Large aperture JGS2 mirror is one of our main products, the diameter can reach 2000mm. We can also design and manufacture custom CGH for optical metrology, surface accuracy can achieve 1/100 wavelength or better.
Material Description
JGS2 fused silica material has been one of the best choices for astronomical telescope mirrors with its cost-effective price and stable optical performance.
The mechanical and thermal properties are as follows:
| Mechanical Properties | Thermal Properties | ||
| Density | 2.2 g/cm³ | Strain Point | 1085 ℃ |
| Compressive Strength | 1100 Mpa | Softening Point | 1640 ℃ |
| Bending Strength | 67 Mpa | Annealing Point | 1190 ℃ |
| Tensil Strength | 48 Mpa | Specific Heat（20~350℃） | 670 J/(kg·℃) |
| Poisson Ratio | 0.14~0.17 | Thermal Conductivity（20℃） | 1.4 W/(m·℃) |
| Young's Modulus | 73000 Mpa | Thermal Expansion Coefficient | 5.5x10¯⁷cm/cm·℃ |
| Rigidity Modulus | 31000 Mpa | Hot Working Temperature | 1700~2000 ℃ |
| Mohs Hardness | 6~7 | Short Service Temperature | 1300 ℃ |
The SiO2 content of JGS2 is greater than 99.95%, so it is also called pure glass.
