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.

Excellent Optical Transmission: High transmittance across the visible to near-infrared spectrum (350nm – 2000nm), making it suitable for most visible and near-IR applications.

Superior Physical Properties: High hardness and excellent chemical stability provide reliable protection for internal precision components.
