Systems With Glass Layers - A simplified explanation of the abstract
This abstract first appeared for US patent application 18347942 titled 'Systems With Glass Layers
Simplified Explanation
- A system with a support structure and a glass layer separates an exterior region from an interior region. - Components, including an optical component, are mounted in the interior region. - The glass layer has a first area that overlaps the optical component, serving as a window for the optical component. - The glass layer also has a second area surrounding the first area, which does not overlap the optical component. - The first area is selectively weakened relative to the second area to prevent excessive glass fracturing during a damage event. - Selective weakening can be achieved through laser-induced-damage features, local thinning recesses, and/or deposited thin films like physical vapor deposition coatings.
Potential Applications
- Optical systems - Protective barriers for sensitive components
Problems Solved
- Preventing excessive glass fracturing during damage events - Maintaining optical component functionality in harsh conditions
Benefits
- Enhanced protection for optical components - Improved durability and reliability of systems - Reduced risk of damage to sensitive components
Original Abstract Submitted
A system may have a support structure and a glass layer that separate an exterior region surrounding the system from an interior region. Components may be mounted in the interior region. The components may include an optical component. The glass layer may have a first area that overlaps the optical component and that serves as an optical component window for the optical component. The glass layer may also have a second area that surrounds the first area and does not overlap the optical component. The first area may be selectively weakened relative to the second area to prevent excessive glass fracturing during a damage event from obscuring the optical component. Selective weakening may be provided with laser-induced-damage features, recesses from local thinning, and/or glass-weakening deposited thin films such as physical vapor deposition thin-film coatings of inorganic dielectric.
