Sapphire Step Glass Windows

Steps increase mechanical strength and reduce the risk of window deformation in high pressure or vibration environments. Suitable for high mechanical stress scenarios such as aerospace and on-board optical systems.

What are the design considerations for step glass windows?

Tolerance control of step height and width.
Compatibility with mounting structure.
Compatibility of coefficients of thermal expansion.
Requirements for flatness and parallelism of optical surfaces.
Environmental sealing performance (if required).
