Gelest provides a wide-range of index materials based on silicon, germanium, tantalum and other metal-organics for direct use or by thermal or hydrolytic conversion. These materials are used in step-index, gradient-index or quarter-wave stacks. Applications range from AR-coatings to Bragg mirrors and reflectors.
- Applications
- Source by hydrolysis of SiO2 and sol-gel derived glasses.
- Intermediate for silica spheres with controlled dimensions.
