Double-sided polished circular stepped windows made from high-quality optical quartz glass (JGS1, JGS2, JGS3) and Corning 7980 fused silica materials, precision-machined to the highest standards. Featuring a unique stepped structural design – a concentric smaller-diameter step is precision-ground on the larger-diameter substrate, creating a self-centering positioning structure for flush-mount installation.
K9 Glass Stepped Windows – Custom Machined, Double-Sided Polished
K9 Stepped Windows are built upon standard K9 glass window substrates by adding one or more stepped ring structures, enabling them to simultaneously meet the dual requirements of optical protection and precision mechanical assembly.
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.
Stepped windows are used in a wide variety of applications where spectral isolation is required.
